Emulation
For backwards- and crossproduct compatibility, several files in dev_flash are available/used.
ps1emu
Note: not available in early Tool/DECR and Debug/DEX firmwares.
Files
ps1_emu.self (1.02++) ps1_netemu.self (1.70++) ps1_newemu.self (2.10++) ps1_rom.bin (2.10++)
Manual starting SELF method
- Insert PSX/PSone disc (region/pressed doesn't matter)
- Start MultiMAN (e.g. 2.07.01++)
- Since 02.07.05 the PSX and PS2 discs are properly detected. PSX discs will show in XMB Game Column and you can launch the PS1 game from there. It uses ps1_emu.self default (you can choose Load or Load (Net), latter uses ps1_netemu).
- Switch to filemanager mode
- Browse to /dev_flash/ps1emu
- Select either one of the ps1 emulation SELF files
Note: Some games run better with ps1_emu.self (e.g. Motal Kombat) while others run better with ps1_netemu.self (e.g. Resident Evil 3). If it doesn't work, try another ps1 emulation SELF file.
Downside: memory card options are unavailable unless you created a Virtual Memorycard before starting MultiMAN (XMB::Category Game:: Memory Card Utility (PS/PS2) > Create a PS1 memory card. Set it to Slot 1 (Press Triangle while selecting the Memory Card, then Assign it). Note: naming it "Internal Memory Card" sometimes works better than other names.
Changes in MultiMAN 2.07.00/01 for ps1_emu handling
These options where needed to make above work:
- Added: LV2 access rights to use LV1 Storage Manager (syscall 864)
- Added: LV1 patch for user access to sys_storage functions (syscalls 600 to 623)

problematic, see Mathieulh quoted below
The main issue here is that it's mostly not doable to emulate the GS efficiently with the rest of the hardware because the RSX is just not meant for this task and cannot emulate the GS on its own while all the available SPUs and the PPU are already mostly fully used to emulate the rest of the playstation 2 hardware, this explains why sony never could finish the ps2_softemu and that it reached a stalling step. I honestly have no idea on how it would be possible to get over the ps3 hardware limitations to perform a full ps2 emulation without any of the ps2 hardware present on the console, one thing for sure is that the emulator would have to be entirely rewritten and optimized like no other ps3 software has been. |
