>>55682734The OG GBA's didn't have a backlight. The AGS-001 SP's are front-lit while the AGS-101's are backlit and considered the best. Don't bother looking for a 101 unless you already have one, they're going for around $200 right now and new ISP screens are better than that of the 101. Hope your not afraid of modding.
Pic related is my 101 on the lowest light setting.
