SCUMMVM to BVM question

Unread post by slai50 »

For those who are using mister with BVM monitors, if you run SCUMMVM on a mister connected to a BVM-20F1U, will there be black borders around the picture or will it be full screen?

At a guess, because i'm not using it myself... it's a linux script, not an FPGA core. So it might not want to run in anything lower than VGA 640x480p. Which won't show up on your 15kHz BVM.

The one thing you could try is simply typing into the config file for Scummvm, but that might only affect the internal resolution, not the resolution the mister is outputting. Or you could try forcing a 320x240p mode in mister ini, and then running scummvm and seeing what happens.

Hopefully someone who knows more can chime in.

ScummVM on MiSTer runs at Main/menu resolution, so whatever it's set to, ScummVM will follow.

Pretty sure BVMs can scan up to 640x480.

BVM F-Series look like 15khz (240p/480i) only.

Most BVMs are only 15kHz. 640x480@60i is still 15kHz, but 480p is not. I'm not aware of the MiSTer using interlaced modes at all... though i suppose there's nothing stopping a core from doing it directly. I just don't know of any current ones that do it.

The (later) BVM's from the D and A series are multiformat.

Full screen, just have to modify the scummvm install to run at 240p akeley posted the link. Can do the Same with ao486, though the DOS prompt is illegible and for both you have to change the .ini settings back and forth for regular usage. fun to do, but not practical for long term use.
