Title: Windows 7 Direct Draw resolution switch fix
Post by: sean_sk on October 06, 2014, 09:10:34 am

Hi Calamity,

Is it possible to incorporate your Windows 7 ddraw resolution switch fix into other builds of MAME. Reason being is that, whilst Groovymame is my main build that I use for my cab, my friend and I like to play online with each other via our cabs using Mamehub which uses its own MAME build called CSUME.

Since I have an AVGA I use the AVRes app to generate ini's for each game which allow res changes for CSUME. Only thing is that I have to switch to a progressive resolution prior to running CSUME so I don't get the ddraw error. The issue with doing this is that being in a progressive resolution such as 288 lines makes using the Mamehub front end impossible since it doesn't scale well.

Therefore can your fix be applied to CSUME or is it unique to switchres only? I wanted to attempt this myself as I know you won't have the time for it. Are there alternatives?

There's totally possible to port that feature to any other version of MAME. However, it won't be straight forward because the involved functions relay on the modeline structures used by GM, so you'd need to rewrite those.
