Linux & RetroArch i have some dunnos

inukaze · 4 September 2017 18:27

Hi there again i have a couple dunnos with retroarch

1 - Where is the “default” value of “system_dir” (BIOS / Firmware folder) i had read too many tutorials on internet, for use bios, and all says “put on the system directory of retroarch” , this should be “~./config/retroarch/system” ?

2 - Which BIOS file for which core are current supported, someone have a list with checksum included in MD5 ?

3 - Why when i run games with MAME (2000, 2003, 2010) this create folders on my home, with the follow names : “cfg” , “diff”, “nvram” .

How i can make the RetroArch create that folders on another places, or use “~/.mame” or “~/.config/retroarch/mame” ?

4 - How i can calibrate my gamepad for certain games of mame, specifically “San Francisco Rush” , “Cruis’n USA”, “Outrun”. because is too much sensitive when i press the analog or dpad ?

5 - PicoDrive can’t boot thought BIOS file like the “Genesis GX” ?

6 - Why too many games of Sega Master System can’t load achievements when i use “Genesis GX” core (with Hang-On Japanese Verified works) ?

7 - PicoDrive can’t emulate the Sega Master System Light Phaser ?

8 - why when i try to run some game with Reicast, ever terminate with “Bus error” ?

9 - In a future version of RetroArch can be included the “MicroEmulator” core ? that is a abandoned emulator of old Mobiles, Java Jar Games.

10 - The Sega Saturn emulator is normal, be slow ?

11 - Why when i run a game with another core, this replace the battery files (sav or srm) with the new core ?

i think the cores must use the same type of battery files, for share saved games between cores.

Thanks for read

change retroarch system directory. this will change it for mame2003, at least

hunterk · 4 September 2017 15:39

I’m not sure if there is a system directory by default. If so, it would be in ~/.config/RetroArch. If not, you can make one wherever you want. If there is a default location and you don’t like it, you can make it anywhere, just make sure you go to settings > directory and point your system/bios directory at it.
you can look in the core info files (load the core but not any content, then go to main menu > information > core information) and it will list any BIOS images and whether they’re in the right location. If you open those files in a text editor, the checksums are listed, as well.
see dankcushions response
I think you can do it via a mame.ini file, but some MAME cores won’t save it when you re-map through the MAME interface, IIRC.
dunno, probably not.
not all cores support achievements, but at least one core for each system should.
dunno, probably not.
Reicast just doesn’t work with some games. When it works, it usually works well. When it doesn’t work, there’s not much you can do to change it.
is it open source? if not, there’s pretty much no chance. If it is, it’s possible, but there are no plans for it currently.
yes, both beetle-saturn and yabause are very slow.

It uses the same BIOS files as Genesis Plus for the CD system. bios_CD_U.bin/bios_CD_E.bin/bios_CD_J.bin. I don’t think it supports using a Master System / Game Gear BIOS file.

You should use Genesis Plus where possible because it’s more accurate and has more features, minus 32X emulation.

The problem is with “MAME 2010” ever create that folders inside home directory. well with “MAME 2014” i can’t use it, ever give me an “bus error” and close retroarch.

9 - Is it open source? if not, there’s pretty much no chance. If it is, it’s possible, but there are no plans for it currently.

Yes is OpenSource and looks like abandoned :v MicroEmulator

Can you run MAME 2014 through gdb?

That’s a known issue: https://github.com/libretro/mame2010-libretro/issues/14

sergio-br2 · 9 September 2017 16:16

Type ‘bt full’ after the crash in gdb, it’ll give some useful backtrace

Do you have the right ROM, BIOS & DEVICES (like qsound.zip) set for MAME 2014? Search for 0.159 version or newer (mostly)
