+Stephen Posted February 17, 2021 Share Posted February 17, 2021 Damn - I see a competition coming up with the 8-bit (ANTIC/GTIA) folks. We pick fights all the time. We generally lose them. But we like to swing. So - um yeah, bring it All kidding aside - very nice looking stuff, I just got a DragonFly cart, so my real 7800 is going back on the shelf. Hope to see some of this on a real CRT soon. 1 3 Quote Link to comment Share on other sites More sharing options...

Eagle Posted February 20, 2021 Author Share Posted February 20, 2021 @Philsan @Stephen try this one Maybe one day @ilmenit will make RastaConverter versions for the Atari 7800 ? Wonderland by @Piesiu Commodore+4 https://tomseditor.com/gallery/i/33068/wonderland-by-piesiu&lang=en DLI only changes 3 colors per line, but that's enough.

SlidellMan Posted February 20, 2021 Share Posted February 20, 2021 That has got to be the best use of the 7800's color palette. You and Piesiu should consider making an actual game with your assembly knowledge. 1 Quote Link to comment Share on other sites More sharing options...

Synthpopalooza Posted February 22, 2021 Share Posted February 22, 2021 I am still curious to see what you can do in 320B with Kangaroo mode. But yes, you guys should try to make a game. Even a port of Robbo would be great. Quote Link to comment Share on other sites More sharing options...

Robbo, but with the TIA music from Robomechanik. Not just because it's a great tune, but because it'll lead to all sort of questions about that thing 7800 programmers love: POKEY + TIA sound (Seriously, though, it has to be one of the better TIA tracks. Would be awesome in Robbo, even if ported to POKEY.) Quote Link to comment Share on other sites More sharing options...
