Cài này em chỉ đọc sơ qua.. vì vốn Tiếng anh có hạn.. anh TIk hoặc anh phuthuy vào dịch phần Readme xem nó ra sao cho anh em thử phát PspStates Experiment v2 for PSP SLIM ------------------------------------ Changes in V2: ------------- - Fixed important bug in inter-thread code (semaphore wasn't waiting due to interrupts disabled), that caused the load state to not be completely read in some cases. This caused black screen after state load (unless you just saved that state, in this case state was still in ram), or even worse, game not working properly due to partial load. - Added states per game basis. The controls are slightly different: old controls now do a local savestate/loadstate of the game, while pressing additionally select button will save/load a global state. See instructions for more info. - Fixed bug that caused normal sleep mode waking up inmediately. - UMD discs and isos in normal UMD mode are now supported. However, they require to nullify umdcache, by flashing one file, read the instructions below. Remember that states of the old version are all globals, and you need to press select addtionaally. Also, remember that when doing the load state of a state saved in previous version, the plugin in ram after the load will be the old one, so it is probably better to discard old save states. -------------- Please read carefully this readme before proceeding to use this plugin. There are some small changes in the readme of this version. Note: The author will not be responsable of any kind of damage to units or of data loss (including game data loss) that this software may cause. This is true for all my software as they are free, but in this case I would feel like I would indicate it explicitily. It is recommended that you backup the nand and important data of memory stick before using this plugin, in order to avoid posible loss of data. This program was never intended to be part of M33 cfw, it always was planned to be released as a plugin, just to clarify :) This software is experimental work and it may behave incorrectly or not work in all cases. Requisites: ----------- - 4.01 M33, 1 or 2, doesn't matter. - A good memory stick is recommended. Fake memory sticks are... fake... and shit, they could make load and savestate too slow. Instructions: ------------- Copy seplugins folder content (IMPORTANT: including the empty folder SAVESTATE, as the plugin will not create it) in /seplugins and activate the plugin using the recovery. This plugin at the moment will only work in game mode, don't bother to use it in pops or vsh. If you plan to use the plugin for UMD's or for isos in normal mode, then you will have to flash the file umdcache.prx in this directory, in /kd using usb flash0. Just disabling the Umd cache in the XMB may not work properly, it is safer to flash this file. Of course you will loose umdcache. This file is not coyrighted, it is just a dummy module with the name of a sony file. SaveState procedure: -------------------- - To save a state, press the home button in game, and once in the home button screen, press R plus one of the followings buttons: up, down, right, left, square, triangle, cross, circle or start. Each of this button is considered a "slot", so you can have up to 9 states. Unlike in previous version, there are now .local and global states. Local states can be loaded only in the game that saved it, and global ones can be loaded in whatever other game, as soon as the hardware (same disc in case of umd0s,a memory stick with same iso path in case of isos) is present. Local states are the normal behaviour: while pressing R in the home button press one of the slot buttons. Global states: while pressing R+select, press the slot button. - At that moment, the PSP will go to sleep mode and return automatically inmediately. - After the quick sleep mode return, you will see a black screen for some seconds, don't worry it will end. The time can vary depending of games and cpu speed, at this state the program is copying ram from one place to another. - When the screen is turned on again, you will see the memory stick led blinking for some time: this is the write of the file. If your memory stick is good, this step should be quick. - The state is saved, it can be loaded during the game or in another game session. (if memory sitck is same or with similar content, you can load other game states withing a game). The state is saved to one of the followings files: For global states: ms0:/seplugins/SAVESTATE/globalstate_u.bin -> up button ms0:/seplugins/SAVESTATE/globalstate_d.bin -> down button ms0:/seplugins/SAVESTATE/globalstate_l.bin -> left button ms0:/seplugins/SAVESTATE/globalstate_r.bin -> right button ms0:/seplugins/SAVESTATE/globalstate_q.bin -> square button ms0:/seplugins/SAVESTATE/globalstate_t.bin -> triangle button ms0:/seplugins/SAVESTATE/globalstate_x.bin -> cross button ms0:/seplugins/SAVESTATE/globalstate_c.bin -> circle button ms0:/seplugins/SAVESTATE/globalstate_s.bin -> start button For local states, if the game is an umd or an iso, it will use the gamecode, if it is a homebrew, it will use the first 9 characters of the homebrew directory. Examples: ms0:/seplugins/SAVESTATE/ULES00818_u.bin -> up button ..................................................... ms0:/seplugins/SAVESTATE/ULES00818_s.bin -> start button The size of the file may vary depending of the game, as it is a 36 MB dump compressed. Tests show that the most expected range is: 10-20 MB. The plugin will not check free space, you are on your own on that. Lcoal and global save states share exactly the same format. If you want to convert one to the other, just change the filename properly. LoadState procedure: -------------------- - To load a state, press the home button in a game, and once in the home button scree, press L plus one of the slot buttons mentioned in savestates to load a local state, or L+select+slot button to load a global state. - In that moment, the memory stick led will blink. This step should be fast on good memory sticks. - After that, the psp will go to sleep mode and return automatically quickly. - The screen will be black for some moment, this wait moment is much faster than the one for savestates. - Once the screen is turned on, and if all went fine, your system will be now in the state in which you saved it. Comments -------- - The current release is a 4.01 M33 specific plugin. It won't work in a future firmware without an update, unless that firmware has highly similarities with 4.01. - For faster operation, it is recomended that you set speed to 333 for game in vshmenu or recovery. - With global states, you can load the state of any other umd, iso or homebrew, as soon as isos are really in the same memory stick or similar path, or in case of umd, the disc is present. Do not change name or path of isos or homebrews after saving a state. - A load state is a REAL LOAD STATE with all the consequences. Lets say you are playing an iso game in march33 mode with the plugin X activated and plugin Y desactivated. Then, in another sesion you are playing that game (or another, as doesn't matter), in np9660 mode with the plugin X desactivated and the plugin Y activated. When you load the state, the game that was saved will still be in march33 mode with plugin X activated and Y plugin desactivated. Because the load state even restores the own pspstates plugin itself, this also causes the "plugin self-downgrading" problem commented later. - This plugin is not compatible with any homebrew or plugin using the memory extended size of the slim. pspstates can be enabled while using them, but then it SHOULD NOT BE USED. Interoperability ---------------- - Interoperability between different sony version numbers: this won't be supporte due to technical reasons. If you were in let's say in a future 4.10 M33 and you want to load a state saved in 4.01 M33, even if the plugin is updated to work on 4.10 M33, it will probably crash loading that state. - Interoperability between different M33 version numbers (4.01 M33, M33-2, M33-3...): there shouldn't be problem with this. After load state, the system would be temporally downgraded in ram, until you exit to vsh. - Interoperability with future versions. Because this software is still experimental, future versions could change savestate data format. Even if it doesn't change, the "plugin self downgrading" problem still exists: you have saved a state in version 1, and then you load it in version 2, the plugin in ram after the load state will be the version 1. - Interoperability with other psp's. Probably not a good idea to share savestates between psp's... they could cause hardware incorrect answer or data loss. The only test done has been PSP1: TA-085, PSP2: TA-085 v2. The PSP1 saved the state. The PSP2 loaded the state. The state load apparently worked, but the game, which was controlled by analogic pad, wasn't answering properly to controls. Wether this was caused by different mother boards or other reasons it is unknown. Anyways if you want to proceed to do more tests, do it on your own, but have in mind some things: * Functional issues: the hardware should be the more similar possible. The isos or homebrews should have same paths. Better not to have another plugin activated. * Privacy issues: The savedata may contain in plain text or compressed, wep or wpa keys. Also, if the XMB didn't clear properly the ram, there exist the possibility too of the savedata containing filenames or even binary data of media that was played in the XMB, which can be recovered using computer forensics. * Legal issues: The savedata contains code of sony kernel, and code of games, so it is probably illegal to share them. FAQ ---- Q: Why only PSP SLIM? A: In the current implementation, I'm using slim extra memory. The file writing is post-poned while file read is done before the real load state. This is because we lack of a good memory stick driver that could be used in situations where the kernel is off. The only memory stick driver we have, which is the used in DC, is extremelly slow, it has no sense to use it here. Until memory stick dma code is reversed, it is impossible the implementation on psp phat. Q: After doing a savestate, sound stopped working A: try to load the state you just saved to see if this fixes. This may happen sometimes in some games, it is not 100% sure, but the reason identified in tests seems to be: the write of the file. In the current implementation,the plugin performs the real savestate after returning from the induced sleep mode code, compressing it in from one ram to temporal one, then original sleep mode return code is executed,and when the system is stable, the file is written. It seems some games or some sony code may not like that such a big file is written, probably due to the time it may take. If some day, the DMA memory stick driver is reversed, this problem should be gone too... hopefully :) Q: What happens if I load a state that doesn't exist? A: If the file to load doesn't exist, the last state loaded or saved in the current session will be loaded as it still remains in ram. If no state was previously loaded or saved, then, black screen :) Third party licenses -------------------- This program uses the FastLZ library, which is relased under MIT license.

Cái plugin này chỉ dành riêng PSP Slim thôi (theo như người viết ra và ở đây chắc là Dark Alex nói là Slim nó có extra memory nên mới dùng được ). Cái này dùng để save giữa chừng khi đang chơi game (hữu dụng khi chơi mấy game save theo checkpoint ). Người phát triển cũng khuyến cáo nên dùng thẻ nhớ xịn, nếu phải hàng fake thì sẽ rất chậm, gây khó chịu. Đặc biệt lưu ý: các bạn nào hơi yếu tim thì đừng nên dùng, ảnh huởng đến sức khỏe mình ko chịu trách nhiệm Cái plugin em up ở dưới đây . Các bác down về xong giải nén ra, copy folder seqplugin vào trong folder chính của thẻ nhớ ms0:\ ấy. Rồi vào recovery mode để enable . http://ifile.it/6qxg2no Cách sử dụng như sau: Khi đang chơi game, nếu muốn save, ấn vào nút home rồi giữ R rồi ấn lên xuống trái phải, vuông tròn tam giác X hoặc Start để gán Slot. Như vậy tổng cộng chúng ta có 9 slots tất cả. Muốn load thì lại ấn nút Home rồi giữ L + 1 trong các nút ở trên để load slot. Các bác cẩm thận ko nhầm . 1 Cái tiến mới của bản 2 này so với bản 1 là có 2 kiểu save slot là local và global. Ở trên là cách save và load local. Em chả biết dịch tế nào để cho sát nghĩa và dễ hiểu nên em để nguyên tiếng ANh . Local có ưu điểm là khá nhanh (so với global) nên đỡ gây thót tim . Tuy nhiên, nó ko thể load được game khi đang chơi game này muốn nhảy sang load game khác như global (cái này em khuyến cào nên sử dụng vì cần quái gì phải đang chơi game này lại phải nhảy sang game khác, mất thời gian + gây tổn hại đến sức khỏe do lo sợ hỏng máy ). Còn save Global thì save = cách ấn home rồi giữ R+ Select + Slot như ở trên. Load thì L+ Select + Slot. Cái này được cái có thể đang chơi game này có thể load và nhảy sang game khác. Tuy nhiên, nó khác chậm và gây thót tim với người sử dụng. Em sợ chết vẫn mới dám thử có 1 lần . Cái này cũng chỉ có 9 slot thôi, nhưng yêu cầu khi nhảy game là iso hay umd vẫn còn ở trong máy, nếu ko có thể gây hư hỏng . Ngoài ra, khi đã save slot, bất kể local hay global đều ko được đổi tên iso, nếu ko nó sẽ ko load được và có thể dẫn đến hư hỏng dữ liệu. Em cũng xin miêu tả về cái sự lo lắng nơm nớp khi save global : -Sau khi save slot, máy sẽ tự động vào chết độ stand by rồi bật lên ngay lập tức. Lúc này máy sẽ hiện màn hình đen 1 chút (lúc này máy đang copy dữ liệu từ ram của psp) -Sau đó, màn hình sẽ bật sáng và đơ 1 chút, đèn thẻ nhớ sẽ nhấp nháy liên tục (lúc này nó đang tạo file save, nếu thẻ nhớ xịn thì sẽ nhanh thôi ). -Bây giờ bạn đã có thể load game ngay cả khi đang chơi game khác. Đấy, kể ra cũng hơi hơi sợ, nhưng nếu quen voọc máy thì ko sợ . Dân chơi ko sợ mưa rơi nhỉ ). Bài này của bạn hoang_lh94 bên 4rum TCDT thấy hữu ích pot cho pà kon :devil::devil:
Khiếp, đọc chi tiết bài viết hết dám test Thôi thì chịu khó đợi thời gian sau vậy, giờ vẫn chưa có nhu cầu vào bệnh viện tim :devil:
