Are there any software option for RGB v. Peak? Maybe I must create a new sd just using the image and config as ofiicial guide since also cps1 running at same level of the MVS on this cab with this setting.Ok, great, but the issue that remains is that your MVS board and MiSTercade have different video output levels, which isn't ideal. I measured an MV1C when developing MiSTercade and its video output levels are very close to mine (3.3V vs 3.0V). The circuit I'm using for RGB video amplification is 1:1 with a very popular arcade platform and I haven't had many other users with brightness issues. Do you have other original arcade games you can compare against? Arcade video can be up to 5V. Cheers!
