This game was tested with r3426. The problems encountered in God Eater 2 Trial/Prelude Edition also occur on this game. I have tried testing the Original (Ver 1.00), Ver 1.01, and Ver 1.10 of the game and there are problems loading the latter two on JPCSP. The SAVEDATA created by JPCSP (using Crypto) does not work on a real PSP.
As mentioned before, Ver 1.00 of this game has problems being run on JPCSP. One needs to enable "Ignore invalid memory access (not recommended for test reports, but improves performance)" and "Ignore unmapped imports (not recommended)" in order to progress further in the game. After starting the Second Mission, JPCSP will be stuck on the loading screen, without those options enabled. Players should activate "Disable optimized VertexInfo reading (may improve compatibility)" during cutscenes to block any graphical garbage that may appear (it may depend on one's Graphics Card). There are lines that may appear in the game when the resolution is greater than 1x. It seems that there are problems with activating Continue (Multi) on one computer with two JPCSP's running simultaneously. At the Session Screen (3rd Screenshot), the first JPCSP will load fine while the second JPCSP will crash with a boatload of errors.
On Ver 1.01, the game will not load normally on JPCSP. JPCSP will display "Critical error: Check console output for details." as soon as the game is loaded. After a workaround, I can load the game normally, but I run into a roadblock after a certain point. After starting a New Game, I can view the first two cutscenes in the game before a message about the PlayStation Network appears (7th Screenshot). After this message appears, I am prompted to save and then the game goes back to the Title Screen. Attempting to load the SAVEDATA will cause an endless loop of what I had previously described. JPCSP seems to either ignore or can not read the SPRX Files (either encrypted or unencrypted) in the GAME Folder (NPJH50832) for God Eater 2.
On Ver 1.10, the game will not load normally on JPCSP. JPCSP will display "Critical error: Check console output for details." as soon as the game is loaded. After a workaround, I can load the game normally, but I run into a roadblock after a certain point. The game seems to load normally until a message about the PlayStation Network appears (8th Screenshot). There is an endless loop of Invalid Memory Addresses and Unmapped Imports. JPCSP does not seem to be able to load the SPRX Files (either encrypted or decrypted) in the GAME Folder (NPJH50832) for God Eater 2.
PPSSPP can load either Ver 1.01 or Ver 1.10 of the game normally, but will crash as soon as the player moves. If one modifies the Source Code, the player can move freely, but the emulator will crash once they attempt to start a Mission. Some interesting tidbits: https://github.com/hrydgard/ppsspp/issues/4545
There are three questions I have been wondering about for awhile now.
1) Why does JPCSP have trouble loading games that are updated/patched without a workaround? Is there a way to find the source of the problem? This seems like an unusual problem since PPSSPP can load nearly every updated/patched game without any issues. Toukiden seems to be one of the very few games that JPCSP does not need a workaround in order to load, with the exception of Ver 1.06 which still has trouble loading as of r3426.
2) Will there eventually be support for all Update/DLC Files (EDATA, PGD, SPRX, etc.)? As stated earlier, JPCSP seems to have trouble with certain types of Update/DLC Files which prevents games from being able to load or progress in further parts of a game.
3) Are there any fundamental differences in code between the way that JPCSP and PPSSPP creates SAVEDATA? What allows SAVEDATA created from PPSSPP to work on PSP while SAVEDATA created from JPCSP causes the PSP to display Corrupted Data?
