Alex Evans’ BASIC UTILS change everything – part 2

March 28, 2023 Sub-Etha Software

See also: part 1, part 2 and part 3. In the first part of this series, I didn’t explain who Alex Evans is or what his BASIC UTILS are. And I may not in this part, either. Rest assured, Alex Evans fans, I will be getting to this soon eventually. …

Nouveauté Macintosh : Lunar Rescue

March 26, 2023 Rhod's collection blog

Enfin ! je termine ce petit fullset de l’éditeur PRATICAL COMPUTER APPLICATIONS INC. Il aura fallu plus de 10 pour mettre la main dessus… Vu deux autres fois à 1000$ neuf, et 450$ Mac Golf, Mac Golf Classic, Mac Courses, Mac Raquetball, Road Racer & Lunar Rescue …

Scoring differences in Super Xevious, and a ‘cheat’?

March 24, 2023 Retro Ports

Quite fortuitously I decided to watch a YouTube video of someone playing Super Xevious to see the new objects in action as they were intended – ie. on a non-patched ROM. The video features the score reaching 9,999,990 which is when the game starts to crash… Halfway through the player …

Native Two Joystick Gameport Support

March 24, 2023 Lukazi's Loot

Did you know that the Apple II computer contains native multiplayer non-keyboard support? Over the years I’ve documented this functionality being done with digital joysticks but since I’ve also been involved with native two joystick game enhancement projects, I figured it was a good time to document these as well.All …

Super Xevious post mortem.

March 22, 2023 Retro Ports

I’ve finished testing the Super Xevious transcode additions. I can only say that Super Xevious was a half-arsed, almost apathetic exercise that couldn’t have taken more than a week. The main enhancement is the increased difficulty (table entries), and the new objects don’t really add much to the gameplay experience …

Alex Evans’ BASIC UTILS change everything – part 1

March 21, 2023 Sub-Etha Software

See also: part 1, part 2 and part 3. Or at least a lot of things. Or perhaps just one thing, but it’s pretty darned spiffy thing. I’ll get to that shortly eventually. But first… Typing in BASIC in BASIC When it came to typing in BASIC, my Commodore VIC-20 …

Super Xevious transcode complete! Now to squeeze both into the same binary…

March 21, 2023 Retro Ports

I’ve finished the Super Xevious transcode, though I’m yet to test the new objects. To give you an idea of how little code has changed, MAIN has 10 uses of an assembler directive to differentiate code, whilst SUB has only 2. These are mainly for title screen and high score …

Amiga performance, Super Xevious ready for transcode, and Donkey Kong updates.

March 20, 2023 Retro Ports

I’ve been playing around with the (transcoded) Xevious source in order to facilitate better performance on the Amiga. I think I was somewhat successful. On the original machine, the MAIN CPU gets a VBLANK interrupt and updates the lower 32 (ground-based object) sprites. It then sets a pair of memory …
