The GBA may have had a tiny LCD display, but these games look damn good on a CRT in 240p

GBA games in general look gorgeous. Even the 3d games work well with the screen.

The F Zero GBA games looked phenomenal both through the GC-GB Player and my RPI through composite.

Metroid Zero Mission looks gorgeous on CRT in 240p or 480i (mGBA Wii emulator), but the 30hz flickering spotlights are painful to look at.
