I was unaware of this douche until just now. I’ve been interested in the Modretro Chromatic for a little while, disappointing to see this guy is tied to it. Glad I haven’t gotten one, thanks for letting people know.

If you want to get a little wild and still play on OG hardware, you could play the Gameboy titles on a SNES Super GameBoy or the Gamecube GameBoy Player. I think the Gamecube one is basically a GBA so it would support all the GB titles. But I’m pretty sure the Super GB only supports original GB, not GBC or GBA. Kinda fun to play them on official hardware hooked up to a big screen, although it will probably look not great lol. Otherwise, you really can’t do better for GB titles than a GBA sp. As for the DS ones, any 3ds/2ds should work just fine for any of those titles. Although gen 6 and 7 run like shit on an og 3ds/2ds. Not sure about modding or flash carts as I’ve only used original hardware or occasionally emulation. To answer your question, you can play all of the titles from gen 1-7 between just a GBA and a 3ds. Those are the easiest way to play them on official hardware.

Several Dragon Quest titles are available on Android. I believe DQ 1-3 are unique versions made for mobile. They are also available on Switch. DQ 4-6 were only ever released in NA on the DS and are damn near impossible to find now for a good price. But the mobile ports are based on this version and it’s probably the most accessible way to play those games. At least if you don’t speak Japanese.
