If possible, only convert the wav files to AAC and keep all lossy files as they are.

I'd say, beside the classics that everyone already listed,

• Legend of Mana (SNES)
• EarthBound (SNES) and the fan translated Mother 3 (GBA)
• Mega Man X (SNES)
• Phantasy Star IV (Mega Drive / Genesis)
• Tales of Phantasia (PSX, not the GBA version)

But there's so many to choose from, it's enough for more than a life time :D

I grew up in the 1980s and I loved my original brick Game Boy. I have all the accessories like the lense and the front light etc. My parents wouldn't let me play video games on the TV so I never got a SNES or Mega Drive etc. Later I got the original psx on my own but that was in 1997 or 1998 when Final Fantasy 8 was released in Europe.
