Ok
As far as I know the only PAL vc games supporting 60Hz are the Hanabi Festival ones.
Here is a list of them:
* Break In - TurboGrafx
* Cho Aniki - TurboGrafx
* Columns III: Revenge of Columns - Mega Drive
* Digital Champ Battle Boxing - TurboGrafx
* Final Soldier - TurboGrafx
* Gate of Thunder - TurboGrafx
* Gley Lancer - Mega Drive
* Gradius II: Gofer no Yabou - TurboGrafx
* Gradius III - SNES
* Mario's Super Picross - SNES
* Ninja Gaiden - NES
* Ninja JaJaMaru-kun - NES
* Puyo Puyo 2 - Mega Drive
* Sin and Punishment: Successor of the Earth - Nintendo 64
* Star Parodier - TurboGrafx
* Super Air Zonk: Rockabilly-Paradise - TurboGrafx
* Super Mario Bros.: The Lost Levels - NES
* Super Mario RPG: Legend of the Seven Stars - SNES
As this list shows there is at least 1 game for every console.
My question is: would it be possible to inject into one of these wad the NTSC version of another game and be able to play it in PAL 60 on Pal Wiis? Could this be a solution for people without NTSC compatible TVs?
