I looked at the source of lr-bluemsx and the problem is already fixed :
https://github.com/libretro/blueMSX-libretro/commit/a0a63d4f38069872195b8afec442848fdf04f12f

Not sure, right now, if the binary still has this problem but the problem should automatically be fixed when a new binary is shared for the install.

Only the docs would need an update.

@mitu

Thank you - that did the trick.+

@stoogesfan87 asking for roms is against rules

Run a Coleco game with verbose logging enable, then check /dev/shm/runcommand.log to see where RetroArch looks for each game's .cfg.

@fryguy1 Please don't post links to ROMs or ROM sites.
Not sure why this reply was needed, since @Folly already provided a solution in one of their earlier posts, but I guess the more the merrier.

@Thorr69 thanks for the reply; i didn't know about that setting and thank you for sharing, but that's not what's going on in this case. some games for the msx just have the buttons swapped from what you'd expect, like Vampire Killer, as mentioned in the video linked below.

i have a few solutions for swapping a and b now for this emulator, but now i'm focused on mapping keyboard keys to buttons in lr-bluemsx (or adjusting the emulation speed in lr-fmsx), which i'm still hoping to figure out.

this video mentions that the buttons are swapped from what you'd expect in Vampire Killer even if you're playing on an actual msx with a controller (mentioned at timestamp 4:35, which i tried to include in the link):

@mitu FANTASTIC !!!!
Everythings working with lr-fmsx!!! I focused to much on Lr-BlueMSX. For Lr-BlueMSX, It's only playable with keyboard . The joypad working only for Coleco. Not enough gamepad buttons are associated with basics keyboard fonctions. They should enable the "RetroPad Keyboard Map - Joypad - Awaiting description" option in Control menu in RetroArch for MSX.
Thank you

As a matter of fact there are 93 bios files spread in the Machines directory. I'm not sure which are needed, but overwriting the whole directory solved the problem.
Thanks.

@mediamogul
Everything works perfectly, for now at least. Thank you very much!

@majestyx okay do this...put the roms into the the colecovision folder NOT the MSX folder. .now make the blueMSX emulator the default (pressing a button right after loading the rom..then the first choice from the list..

after that it will load just fine and simply...
