That's hardware scaling kicking in. To avoid it, enable "Simulate Scanlines" from the menu. Keep in mind that it will be slower without the hardware scaling.

Pokemon worked normally since the previous update (when VGBA went from 3.5 to 3.6). The problem was with the way misaligned memory accesses were emulated.

Set proper FlashROM ID or EEPROM size using Configuration Menu. If you do not know what these are, use Save State and Restore State options from the menu, ignoring in-game save options.

Personally i think these applications are the best on maemo by far. Install, grab a few roms (legally of course), and hey presto instant gaming satisfaction. Simple. And no annoying slow-downs or quirks that are detrimental to the operation of the application itself either.

My only criticism would be that figuring out where the controls are on the touch screen is a bit of a guessing game (for VGBA).

There should be no state stored in kernel between updates, everything comes in omapfb_update_window structure when ioctl is called including color mode. Looks like kernel bug or some side effect. I'll check it out. That would be pretty unfortunate.

Mplayer handles it fine both in fullscreen and windowed mode, though. It does direct access also in windowed mode and bringing up power key menu or any other menu (statusbar,..) works fine except messing up window of mplayer (which is to be expected).
That's a hardware limitation of Epson LCD controller in N8x0. It supports exactly a single scaled area which works as some kind of magnifying glass. That's why XSP extension does not work as expected on N8x0 when you try to have multiple parts of screen using pixel doubling (it just moves zoomed area). It is OK for video overlay, but is not very suitable for more general use.

PS. Two of the video&graphics related improvements managed to get into the latest diablo 36-5 update: the fix for tearing synchronization problems when running at 400MHz and fast YV12->OMAPFB YUV420 color format conversion.

On MasterGear there were the little boxes drawn onto the screen, is there not something similar for VGBA?

Yes, you are right, this bug still exists in the currently released kernel. It should not affect anything on "normal" system use though, so you can only encounter it working with the framebuffer directly.

"Show Input Cues" from the menu. They are even labeled now.
