why does groovy mame set resolutions twice (smashtv)

[billfor]

I'm noticing that smashtv is playing in the wrong res on my setup. The log file shows that groovymame picks a good one and switches to it, but then it repeats the process and uses the wrong one.

Thanks.

btw the log looks something like:


SwitchRes: Entering switchres_modeline_setup
SwitchRes: v0.015a:[smashtv] Calculating best video mode for 399x253@54.815170 orientation: normal

This is the one that finally gets used and obviously the game looks wrong....

Hi billfor,

GM is just doing what the game is asking for. In this case the game requests 410x256. As you don't have this resolution available in your system, GM virtualizes it using the highest resolution available. So either add this mode with VMMaker (using ReslList.txt) or use magic resolutions so all imaginable resolutions will be at GM's disposal. The reason this mode is not created by VMMaker in the first place is because MAME doesn't report it through XML. It reports 399x256 instead, but the game switches the video mode later, as many Midway games do btw.

Thanks Calamity!

I was using Dynamic Modes rather than the Magic resolutions.  I added 
410 x 256 @ 54.000000 smashtv

and it works great now.

Thanks again.
