Editing Emulation

[[Category:Software]]
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++)

* 1.70:
**Added the ability to play original PlayStation format games downloaded from the PlayStation Store.
**Added rumble functionality for USB accessories which support it when playing PS2 games.
**Saved data from PlayStation format software now usable on both PSP and PS3 systems.
**Backwards compatibility for PS1 and PS2 games was improved.

* 2.10:
**Users can now play PlayStation game discs on a PSP with remote play (this feature was not announced).
**Backwards compatibility for PS1 and PS2 games was improved (Update was also unannounced but evident in Sony's backwards compatibility search site).

=== 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. MultiMAN 02.07.07 seems to solve the savegame issues.

==== 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)

 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.
