NIKON Posted October 24, 2017 Share Posted October 24, 2017 Greetings... This has probably been asked before but how hard would it be to port a 2600 game to the 7800 platform? Quote Link to comment Share on other sites More sharing options...
Andromeda Stardust Posted October 24, 2017 Share Posted October 24, 2017 There's a hidden 7800 game in every 2600 cart. Did you try simply plugging it in and hitting the power switch?! 1 Quote Link to comment Share on other sites More sharing options...

+Allan Posted October 24, 2017 Share Posted October 24, 2017 About the same as porting it to the Colecovision. Allan Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted October 25, 2017 Share Posted October 25, 2017 The 2600 and 7800 are unique beasts - even more so in comparison to each other. Basically all you can reuse directly is the game design. The assets would need an overhaul. The coding would have to be completely re-written.

Andromeda Stardust Posted October 26, 2017 Share Posted October 26, 2017 In all seriousness, the 2600 is an odd beast. It has no display buffer like nearly every other game console, but instead updates the display register every scanline instead of once per frame. So many display tricks on the 2600 are impossible on other consoles including 7800. Only the CPU and audio portion of the TIA are shared between console modes.

DCent Posted October 27, 2017 Share Posted October 27, 2017 7800 is backwards compatible with 2600 but not 5200 games. Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted October 28, 2017 Share Posted October 28, 2017 7800 is backwards compatible with 2600 but not 5200 games. Not an expert but I *think* when you insert a 2600 cart it effectively becomes a 2600. Meaning, you can't "cheat" and use 2600 code for logic and 7800 code to access the 7800 display hardware. So, backwards compatible without sneaky ways to get the best of both worlds. This is unlike the sega genesis where to a point you can try and access sega master system graphic modes, SN76489 (sound) and the z80. 1 Quote Link to comment Share on other sites More sharing options...
Andromeda Stardust Posted October 29, 2017 Share Posted October 29, 2017 Genesis "becomes" a Master System when an MS cart is inserted, does it not? Quote Link to comment Share on other sites More sharing options...
vidak Posted November 19, 2017 Share Posted November 19, 2017 Genesis "becomes" a Master System when an MS cart is inserted, does it not? You need the "power base converter", but yeah, basically. The Genesis has both a 68k and Z80 in it, and the Master System's CPU was a Z80. Quote Link to comment Share on other sites More sharing options...
Osgeld Posted November 19, 2017 Share Posted November 19, 2017 Also the genesis vide chip was a evolution of the sms video Quote Link to comment Share on other sites More sharing options...
