Another update for pergame, the handy homebrew plugin that allows you to load "other modules as if they were in /seplugins/game.txt"is now available for download courtesy of PSP homebrew coder AtomicDryad. The latest release includes some new features, more fixes and various other improvements.

Developer's note:

Pergame is a selective game plugin loader that loads other plugins. The difference from just using game.txt is that pergame lets one load plugins for -specific- games, instead of all games. Thus one doesn't need to toggle a specific module on or off if they only need it to make one game run in m33, and cheat programs that break some homebrew can be told only to load for isos/umds.The configuration system aims to be versatile; filenames, partial paths, and umdIDs can be used as matching criteria. Also, each iso or eboot may have a configuration file named 'FILENAME.plugins' that contains plugins to load (one per line). Games that require m33_620.prx/etc run successfully when using this loader instead of /seplugins/game.txt.

Changelog:

• [major fix] iso detection more reliable; using an m33 function now, direct memory reading by address deprecated. umdID is still detected via memory read until/unless I find a better means.
• [feature] blacklisting modules with '[COLOR="DarkOrchid"]!/seplugins/mod.prx[/b]'. Blacklists must be before the entries they blacklist. The top of local .plugins conf file is best.
• [fix] psp type and firmware version now detected, and memory addresses are adjusted accordingly.
• [fix] autosort no longer autosorts without 'autosort=1'
• [debugging] pergame.txt options added: 'oldisopath=1' (use old memory-read isofinder), umdaddr=0x880137B0 (mem addr where UMDID is found).

Current compatibility (tested) list:
game - module - note
any - freecheat
any - cwcheat
any - psplink - only when loaded from pergame
NOT eboot demo - prometheus
NOT eboot demo - m33_620
KHBBS - khbbs translation modules

Current incompatibility list:
game - module - loaded from - result
iso/umd - macrofire - pergame.txt - game start fails with 0x80020321 (no such device)
homebrew - macrofire - pergame.txt - macrofire menu opens in a loop
any - psplink - game.txt, before pergame - psp crashes, or 0x8002013c (library not found), loads in pergame however
any - psplink - game.txt, after pergame - pergame fails to load some modules (freecheat)
eboot DEMO god eater jp - prometheus/m33_620 - pergame.txt - loads module but fails to work
eboot DEMO phantasy star 2 jp - prometheus/m33_620 - pergame.txt - loads module but fails to work

Installation/usage:
snag: Downloads - pergame - Project Hosting on Google Code
latest svn (bin+src): http://pergame.googlecode.com/svn/trunk/pergame-svn.zip
Throw the prx anywhere and add to ms0:/seplugins/game.txt. put pergame.txt In the same folder
and edit. Syntax is (per line):
module identifier
'module' is a path to a plugin, like: 'ms0:/path/to/a/plugin.prx'. No spaces. Case insensitive. 'ms0:' not required.
if module starts with an '!', like '! ms0:/freecheat/fc_3xx.prx', it will never be loaded for matches.
'identifier' is case insensitve, does not require 'ms0:', can contain spaces, and can be one of the following:
An ISO like: '/iso/name_of_game.cso'
An EBOOT like: '/psp/game/filer/eboot.pbp'
A partial match like: '/psp/game/cat_internet/'
A UMDID like: 'JPJP65535' or 'usls-99999'
All physical UMDs: 'umd'
All ISOs or CSOs: 'iso'
Examples:
# comment
/seplugins/cwcheat/cwcheat.prx ms0:/iso/cat_game/name_of_game.cso
ms0:/freecheat/fc_3xx.prx usls-99999
!ms0:/seplugins/m33_620.prx /iso/cat_newgames/crashes-with-620.cso
/seplugins/m33_620.prx /iso/cat_newgames/
/seplugins/lolmodule.prx /psp/game/cat_testing/lolhomebrew/eboot.pbp
/seplugins/lolmodule.prx /psp/game/cat_testing/lolhomebrew/eboo
See pergame.txt for more examples.
Also, the module will attempt to load the following files, which can contain one module name per line:
/iso/name_of_game.iso.plugins, /iso/name_of_game.plugins, /psp/game/name_of_homebrew/eboot.pbp.plugins,
/psp/game/name_of_homebrew/eboot.plugins
Examples:
'/iso/flow.cso.plugins' or '/iso/flow.plugins' for '/iso/flow.cso'
'/psp/game/filer/eboot.plugins' or '/psp/game/filer/eboot.pbp.plugins' for '/psp/game/filer/eboot.pbp'
Example contents of /iso/khbbs-jp-eng-patched.plugins:
ms0:/KHBBS/KHBBS_patch.prx
!/seplugins/cwcheat/cwcheat.prx
/LOLpr/LOLprCheatDevice.prx
Additional options - case sensitive, no spaces allowed.
autosort=1 - whenever an eboot is launched, make it move to the top of XMB's game list.

Troubleshooting:
If something doesn't load, add 'logging=2' to pergame.txt, and post a bugreport to Issues - pergame - Project Hosting on Google Code with the logfile.

Debugging:
You shouldn't need these options unless something doesn't work or needs adjustment for compatibility reasons.
If you want to troubleshoot yourself, look for 'pergame - isoread' errors in the log and try adding 'oldisopath=1' to pergame.txt. If -that- fails,
or if there are problems detecting the UMDID, a new NID or new address will need to be located. The addresses can be set without recompilation via
the 'isoaddr', and 'umdaddr' options. If you locate new values and fix the issue, please post the values to
Issues - pergame - Project Hosting on Google Code so they can be added to a new version.
logging=1 - log to 'pergame.log'
logging=2 - log ALOT to 'pergame.log'
oldisopath=1 - find the ISO filename by direct memory read instead of the m33 function.
isoaddr=0x........ - the memory address to read. Changes with psp models and FW versions. Not sanity checked.
Example: 'isoaddr=0x88072408'. Make sure the format is correct as the string isn't sanity checked!.
offsetiso=0x........ - find the above address via offset to SystemControl's textaddr. Changes with psp models and FW versions.
umdaddr=0x........ - the memory address to read to find UMDID. Changes with FW versions. Autodetected by default.

Tested with:
CFW 5.00m33, m33_620.prx, stargate.prx, freecheat.

Caveats:
This uses a StartModuleHandler, and I have yet to determine how to turn it off.

Todo:
Find out why macrofire explodes.
Ditch the StartModuleHandler and find out how to better duplicate the m33 /seplugins/ loading methods.
DONE: Fix UMD-IDs and real UMDs.
Fix^H^H^H test np9660 compatibility.
More power-user/OCD/tweaks such as a better autosorter.
Maybe? Automatic on-the-fly prometheus patching via temporary SceIO hooks.
