Great! It worked for me after several attempts , fw 5.1
______________________________________
For those who are having trouble trying to get this to work, this is what I did:
On the pc
- download the files required (files for the emulator) m4xw linked
- look up on google for the bios and download them all
scph5500.bin PS1 JP BIOS - Required for JP games 8dd7d5296a650fac7319bce665a6a53c
scph5501.bin PS1 US BIOS - Required for US games 490f666e1afb15b7362b406ed1cea246
scph5502.bin PS1 EU BIOS - Required for EU games 32736f17079d0b2b7024407c39bd3050
-Create a .cue file for every bin game you want to play, if you don't know how to do that, this is how you do it; (I will use Resident Evil 3 as an example)
Open notepad
type down exacly what its below and change 'resident evil 3.bin' to whatever rom you wanna play;
FILE “Resident Evil 3.bin” BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
save the file as `all` and name it exactly as your bin file is but change the extension to cue, like this
Resident Evil 3.cue
On the Switch
-Copy all the files for the emulator to /switch
-Create a folder on /switch/roms called `Beetle PSX` ( you can name it whatever you want )
-Paste your roms on this folder /switch/roms/Beetle PSX along with the .cue file, so this should be normally 2 files, .bin and another .cue (yeah I know, theres more files the emulator can load, but this is just a newbie tuto)
-Paste the downloaded bios onto /switch/roms/Beetle PSX along with the games
Thats it, there you have it, just load the emulator and have fun
