RetroArch 1.12.0 UPDATE (NOT WORTH IT)
A new version has been released two days ago. I'm just noticing now, and so far here's my findings. But first a reminder that I do not test all cores. I'm just testing the ones I think are the most popular (Arcade / NES / SNES / GB / GBA) and looking if newer updates breaks compatibility with MAME2003, CPS3 and NEOGEO roms.
It's slow when setting up directories. Navigating through folders is painfully slow.
It doesn't save my settings.
Atari (Stella 2014) crashes. Works in 1.11.0
CPS3 1.12.0 won't save my configuration nor save my directories routes... so I can't load roms that requires Cache files. Useless.
FBALPHA works. If I recall correctly it crashed in 1.11.0 (might be confusing it with MAME2000)
Little sidenote; A game called Boogie Wings (Ragtime in JP) can be played with minor slowdowns now. Definitely an improvement over old FBALPHA cores.
MAME2000 works and no longer crashes when changing roms. An improvement over old MAME2000 cores. Not sure if this was possible before 1.12.0 as I got used to actually restarting RetroArch before loading another MAME2000 rom.
Also, in case you didn't knew you can play Robotron, TotalCarnage and SmashTV with C Stick (only with MAME2000), just remap buttons to it and it'll work.
Do as picture shows:
MAME2003 PLUS: Something strange is happening. Somehow Core C just completely stopped working with RA 1.12.0
It's strange as all the other cores are working correctly... maybe my roms got bad when copying? I dunno... and I don't plan to look how to solve this. But just a warning if you too have the same problem.
UPDATE: Further testing shows that indeed 1.12.0 broke compatibility with just that one core, as loading a C-Core game from old cores has solved the issue. When you load a MAME2003 rom, it will load RA 1.7.6 which is the version these cores works under... this means that when you Close Content/Restart RetroArch it will stay in 1.7.6 unless you Quit RA and load it from Homebrew Channel.
GAMBATTE: Still has slowdowns. Crashes with some games.
MGBA: Still has hiccups with some games.
VBA NEXT: Works but somehow they got rid of Rumble feature. Can't remember but old VBA (not NEXT) cores does support Rumble with Gamecube controller in Rumble Featured games such as Pokemon Pinball Ruby&Sapphire and Drill Dozer.
NEOGEO: It's working but as 1.12.0 crashes when saving up directories routes, I can't tell RA where to load Cache files for Large NeoGeo roms... so... useless
NEOGEO POCKET: Works
NES; FCEUmm/QuickNes/NESTopia all are working fine. Choose your favourite.
SEGA; Refuses to work... STILL
PS: RetroArch 1.12.0 refuses to load now.
EDIT: I really don't see the point of doing these "Important Posts" when newer versions of RetroArch has been slowly going to shit. This might be probably the last time I'll try an update for RetroArch Wii as I really don't see the point of even trying when things are getting broken. But feel free to test though...
