Hey I'd like my PAL SMS2 upgraded. The bare minimum is permanent mod to NTSC. Then at least it should be usable on my CRT with a correct RF box.

Though I prefer RGB output (maximum AV quality the system can possibly offer) and 50/60hz switch. ENG/JPN sounds nice too if SMS2 supports that, for the handful of games with differences in Japanese mode.

Also take extra care the cart slot is properly functional. I'm NOT going to happy to see known working games fail to load.
