Running higher-resolution programs

Unread post by mad_ady » Sat Dec 28, 2019 3:04 am

Some programs might require higher resolutions than 320x240 (e.g. Windows 3.1 needs 640x480). Would this trick work on the Advance, crashoverride?

The GO Advance has two hardware image scalers: one in the display controller (VOP) and the other in the 2D accelerator (RGA2). The most typical scenario would be to just give VOP the larger frame buffer (video for example) and let it automatically scale the output to the display. However, the emulators currently use the RGA2 scaler since it offers bicubic (hermite) filtering that produces an amazing picture sharpness.
