If you're using this feature on a PS Vita, select 'Original' screen mode in the Added screen mode adjustment for PS1 games. I have a hand full EBOOTS i must sort through an test before i add them but that's a future plan.- Added custom graphics filtering support for PS1 games. Please login or register to see this link. However this means it cannot be played properly on a PS Vita running Adrenaline, however, use the PCSX-ReArmed RetroArch core instead.
#ADRENALINE MAKE PS1 EBOOT FULLT SCREEN PSP#
** - POPSLOADER is required for this game, as a result, it will work on PSP models with varying degrees of success. This is also why these eboot dumps tend to have bugs or problems: because these tools also copy stuff from the RAM that don't necessarily belong to the eboot. The thing is that the eboot gets both the pfs and the NPDRM encryptions removed when the game is running, so VItamin and MaiDumpTool merely "trick" the system into loading the decrypted eboot into the RAM and then they reconstruct a copy of the eboot by copying it from the RAM, while also adding some stuff like the calls to the mai.suprx file in MaiDumpTool's case. Let me know if you have any more questions~īut as for how the MaiDumpTool and Vitamin work, they basically just employ an old trick: the Vita removes the pfs encryption from the game files, including the eboot, when the game is booted, and it just copies these decrypted files to another directory from the app0 partition the Vita uses to load the game.īut for the eboot, things change: the eboot is protected under an additional encryption layer called NPDRM, which so far no one has managed to break through. Little long winded, hope this was able to clear some stuff up~ The only reason we can "dump 3.61+ games in NPS" is because NoNpDRM can fake a zRIF key, but the actual key to decrypt the game doesn't work, and it fails to launch regardless.
It's all pretty complicated, but in short, all the methods known for dumping are close source, the methods the Vita used to decrypt are not public knowledge, and the keys used for 3.61 are not known. It's like we've made a "Skeleton Key" to a door no one knows how it got there, how it works, or who made it, but the key opens the door in some cases. We had a game with a key, an OS with the Decryption Method, and a means to make the two meet, making the game work. So in short, we have no idea how Sony manages their decryption method in the Vita, as it's not in plaintext code, it's all obfuscated, encrypted, and packed away in processors (f00d, Trustzone, etc), meaning there's no "code" to break per-se. That key is part of the reason we cannot play 3.61+ games on our Vita, because they can't be decrypted/"handshake" with the Vita due to the keys not matching, thus resulting in a "black screen crash" for any game. Meaning everything build with the VitaSDK for 3.61, used a different key than all of them before, making the keys we have for 3.60 and under, useless. Income 3.61, they changed the private decryption key.

The reason we were able to make NoNpDRM games even work, is because back in the day, someone managed to decrypt and publicly release the Keys for PS3 and the Vita, because of this, we knew the "key" to unlock the code, thus, allowing us to dump and engineer methods to use that key to launch the game. f00d, for example, has yet to been publicly hacked (Enso, we believe, is a f00d hack, but it's, again. Well, kinda? We have access to the Kernel, Trustzone, and the Operating System, decrypted and such, however, there are parts of the System not yet touched (publicly). We just know they work, one being from China (Mai) and TheFl0w (Vitamin), and both work in different ways.Īs to "so do we not have access to the whole VITA now?" - Believe it or not, we don't. Due to that, we actually (as a community) have no idea how either of them do their own magic, as the VPK's and Projects are both closed source, and no one has/can reverse engineer the tools due to obfuscation, and the Developers being rather, erm, protective of their work. Both MaiDumpTool and Vitamin (both dumping tools) are closed source.
