The a8disasm is like the "6502bench SourceGen - Disassembling" project, a mini-IDA reverse engineering program. https://www.youtube.com/channel/UCSgyycB_nclcZk3_-CJpxFA -

Graphic mode advice for new game
explorer replied to explorer's topic in Atari 5200 / 8-bit Programming
I am also not able to see it in the atari800 emulator in Linux. I only see the last line of counters. Or maybe I haven't found the right combination of display options. They are enough. -
Graphic mode advice for new game
explorer replied to explorer's topic in Atari 5200 / 8-bit Programming
Then ... the 160x114 screen results in 1/4 or 1/5 of the original screen. It is impractical at the beginning of certain combats (the enemies patrol from one place to another, and when they discover the hero they change their behavior), or when entering a screen, see how a door opens at the other end of the screen. Thank you very much for these tests. They are giving me many ideas. -
Graphic mode advice for new game

There are some images of the development for CPC, but it is not finished yet. It is seen that they are 320x200, 4 colors. https://www.retromaniac.es/2020/01/the-sword-of-ianna-lucira-tambien.html -
Graphic mode advice for new game
explorer replied to explorer's topic in Atari 5200 / 8-bit Programming
It is precisely what I want to avoid. It makes no sense to do exactly the same. What I want is to take advantage of the hardware of the A8, still being the same game, but having "something different" and typical of the A8. And if I can't have the colors of the MSX2, at least try to scroll it, or a continuous map. Or improve animated tiles. What?
