Re: Reverse Direction game for the Commander X16
Hi Keith, thanks! :) And well, no official names as such. I call them: 'red apple dude', 'blue blob' and 'green squid'. But you won't find those names in the source code :) There's also not much difference between them, gameplay wise. Only the red apple dude's fire lasers down at you, but apart from...

Reverse Direction game for the Commander X16
Hello everyone, I just finished a new project, which was to make a real time shooter game. It's called Reverse Direction and it's a clone of a well known game from 1978 :) Really was fun to try and wrap my head around a proper game loop, handle animation frames, slow the game down to run at exactly ...

Re: Video: Lesson 2 - Addressing modes on the 6502
Oh, and the SNES version doesn't crash for me. Sure it complains about a bad checksum in the ROM file, but Snes9X loads just fine for me, with the same results.

Re: Video: Lesson 2 - Addressing modes on the 6502
Hi rumothy, Did you also download the latest sources.7z to go along with the devtools? I just tried running example 2 from the Lesson2_AddressingTest.asm file in my version of the devtools/sources and it ran just fine: it loaded $08 into the assembler, printed the values with the monitor function, t...

Re: hi
Yeah, reverse engineering your way through a decompiled piece of code, without any assembler provided labels or comments written by the original developers is not a easy thing. I've tried decompiling a few 6502 programs, and made some headway looking for RTS calls to return from a subroutine. I was ...

Re: hi
Hi Peter, welcome to the forums!
x86 assembly is very interesting, just not my personal cup of tea. I'm more of a 6502 programmer. What made you choose to go to x86 assembly from programming in a high level language such as VB.NET? Just out of curiosity for how to talk to the hardware?

Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
Hi John, That's a tough one. The definetiles part is fine, if I put the Programstartwithoutclearscreen: label lower, it still corrupts. Something is happening with the FillAreaWithTiles function. But i'm not sure what.... It's like something is corrupting a register or overflowing somewhere causing ...

Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
Hello John, You almost had it. Note, i'm by far not a Z80 programmer (i'm more into 6502), but I got your code working. The problem was in line 24 of your code: ld de,128 Loading the DE register for 128 tiles. But you should load it with 128 tiles with a size of 8 bytes per tiles, so like this: ld d...

Re: SNDH player with pitch visualization for Atari ST
Love the tune
The visualization is a really nice touch (not to mention the exploding disk message had me cracked up )
