I've got some favorites that I feel still hold up.

• The Legend of Zelda - A Link to the Past (SNES)
• Batman Returns (SNES)
• Super Metroid (SNES)
• Final Fantasy - Mystic Quest (SNES)
• Uncharted Waters (SNES)
• Tomb Raider (GBC)
• Metal Gear Solid (GBC)
• Metroid: Zero Mission (GBA)

I own a PSP and PS2 as well, but a quick glance at WebRcade doesn't list those systems.
