Okay, so the only reason that PS2 games won't run is because of the lack of GS emulation.
For PS1, why were devs looking at building an emulator instead of simply mounting discs like they do with PS3 games? Graf recently even revealed the authenication portion of the HV responsible for detecting the type of game in the drive. I would think with a little knowledge, a BM could bypass the check and mount an iso. At least then we'd have PS1 backups for now.
Possibly, modifing the ps1 game to make a psn pill pkg might work. I'll look into it when I get home, but I'm not a PS3 dev, my programming knowledge is for creating websites and Windows programs.
Just so there's something on topic here, has anyone heard of anyone starting the process of porting Dolphin over yet?
My 60GB PS3 can play PS2 and PS1 by disc (backwards compatible) so its proberly easier for those consoles. Doubt anybody will bother because majority are playing on the SLIM. I might have a go at this app developing and make something that can play downloaded PS2/PS1 games (or backups) Time to get learning :cool:
Ok, well after alot of research, I found out why ps1 games were trying to be played through an emulator. It's because of an npdrm protection that we can't currently get around, since all the people with the npdrm key are refusing to release it in fear of being sued.
Basically, there's already 2 emulators for ps1 games on the ps3 (all versions). One plays games from the disc, the other from the hard drive (and has upscaling). The disc one could be circumvented by modifying a firmware self file; but all backups would have to be burnt, and there wouldn't be upscaling. The hard drive one is used for playing ps1 psn games, and has upscaling. In order to use that one, we would need to modify a current ps1 psn pill and use it to boot a different game. Unfortunately, they have a npdrm protected edat file in them, and can't be modified.
Getting into one of those emulators or creating a new one are the only ways of getting ps1 backups on the ps3. It's speculated that a backup manager would not be able to mount ps1 games, because control of the drive is handed over to the emulator after the ps3 firmware detects that its a ps1 game.
All Ps3s are ps1 backwards compatiple right?
so all we need is a bm to boot them!
no emulation is needed (apart from the obviiouly installed one)
just like ps3 i guess.
(not saying it will be an easy task)
maybe we might see multiman do this since it has been done with the ps2 on 60gbs
The speculation is that the BD drive is handed over the ps1 emu, and the emu has no access to the file system of the ps3. Basically, it's shutting down the ps3 functions once a ps1 game is inserted. That's why BMs wouldn't work. If you insert a ps1 game and look in a ftp or file manager, you'll notice that you can't see the data on the disc like you can with ps3 and ps2 games. Of course, all this speculation could be wrong and all we'd need is to find the proper mount point.
Of course, repacking the games to mimic psn ps1 titles would be a better option because the emulator has upsampling, and uses pbp files. We'd need a copy of a psn ps1 game to look at, as well as someone with the npdrm decryption payload to decrypt the iso.bin.edat file......
Upscaling works with disc too, change the setting in the game menu on xmb then try a game you can clearly notice a difference, also if both options are set to off in xmb whilst playing a psone game press the playstation button on the pad and go to video settings and you will only have smoothing, but if both options are set to on in xmb then go to video settings in game and you now have screen and smoothing settings.
what if the mounting was happening in a system process you know the ones that never stop?
and also if the ps3 has the fuction to play ps1 games on its own hardware why softemu the games to a psn won and run it on ps3 hardware, your therories might be right but like all other things we just need to find a way to unlock them , get acess to them. (lol this turned from wii on ps3 to ps1 on ps3)
