Robotron in DOS advancemame, any veterans that can help?

[abispac]

Before you roast me, i found an old pc that natively has 15khz video settings if you use it with advancemame in DOS, there was an old installer "bkst" that made things easyer, the hardest part back in the day, was to burn the gosth image as it took ages to get burned. Anyway, i manage to get DOS and the bkst thing working.

BUt im not here for that, what im trying to achieve here is to use this for a dedicated robotron, with what i have. RGB moded tv, 15khz ready pc with sneskey9 ready to use pc to jamma board, so all fits. The only thing that dont really fits its i cant get robotron to look as nice as it should.

and it looks like advancemame just has a few modlines

Code: [Select]

Thanks in advance for any help.

Hi, according to http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=robotron, the correct resolution is 292x240. So either you manage to install this resolution or use 320x240 with no magnify, no resize at all then adjust your monitor to remove the black sides out of the screen ?

you can try a resolution that is a multiple of 292, if advancemame has integer scale option or keep aspect ratio, like 584x240 or 876x240
