I have had a 7800 for a long time but it's a PAL unit and I've been loathe to invest too much in games for it; reason being the usual PAL compromises from that era giving us a less than optimal game experience here. It's also not that great as an RF video device - my 2600 gives me a better picture. I use a 4:3 CRT with RGB SCART for retro gaming but I still use RF for my 2600 and 7800.
So I'd be interested to know exactly what all this entails. I really like the look of it. I have a PAL 7800, a US 4 switch 2600 with composite mod and a PAL 6 switch + a Harmony. I've also bought a few homebrews such as Pacman Collection and Medieval Mayhem from the atariage site.
I was quite active for a while there creating PAL60 ROMs for 2600 games on the atariage website as well. Have given some feedback on projects that were asking people to run demo programs and give feedback on overscan etc.
So I am somewhat invested in old Atari tech - but I'd be in for this alone if it gave me a way of playing 7800/2600 games using composite with high score support for 7800 games. The real bonus is the homebrew scene. Really like the look of some of the homebrew games - stuff like the Circus remake look great for example.
Given what I have I can jump a few different ways. Is my best way forward to get an NTSC 7800 (modded for composite) and XM or is it an all-in-1 unit?
