Re: Sprite List Code Messed Up

Hey just did some research, and took your advice and reworked the code a bit. Here is what I have so far: ; ************************************************************* ; ClearSprite ; Clears the sprite counter ; ************************************************************* ClearSprites: move.b #0,...

Sprite List Code Messed Up

I am having this weird problem where the sprite is changing randomy and soft locking the game. ClearSprites and AddSprite are both subroutines that I have written myself based on some notes written I wrote based on a conversation I had with Sik. While UpdateSprites is just a modification of LoadSpri...

Re: Code Crashes Emulator

Works at home. Test with blastem, kfusion and genskmod. I also tried to change tile number with TILE_USERINDEX and also works. same source with my binary file. https://www.dropbox.com/s/o1u9wz5ef9d6w5z/source_c_test.zip?dl=0 //we load our unique tile data at position 1 on VRAM VDP_loadTileData( (co...

Re: Need Help With xgmplayer

Given your project i would definitely recommend you to use SGDK as well. It will be far easier than using assembly and XGM will work out of the box. Event if i'm not a fast coder i can replicate what your game is currently doing in a couple of hours with SGDK... Problem is it has taken me longer to...

Code Crashes Emulator

Hi, I am trying to learn the SGDK and am stuck on literately the 3rd tutorial which is drawing a background using tiles. Here is a link to the source code. When i compile it it compiles fine, however when I run it it crashes my emulator. Any assistance in this matter would be greatly appreciated. Si...

Re: Need Help With xgmplayer

Just wanted to give an update as to progress. I have tried to convert start over in c using SGDK per another members suggestion, Unfortunately I am having trouble trying to code even the most basic task(loading a palette). So with that in mind I have decided to stick to assembly language, and try to...

Re: Need Help With xgmplayer

Yeah the wrapper is based around the old BEX code (which itself was mostly asm anyway), doing it from the lastest version would require rewriting the whole lot from scratch =/ Would have been much easier if the game was written for SGDK from the beginning (avoiding the need for this whole thing). I...

Re: Need Help With xgmplayer

When you're coding, do you want a half-dozen people standing behind you looking over your shoulder telling you conflicting instructions of where to go (in the program) and what to do? THAT is what real-time chatting does. When you're asking help to troubleshoot something together, yes >_> (especial...

Re: Need Help With xgmplayer

...why the heck did they think it was a good idea to break that? There's a bunch that's been added to inline assembly over the years, but it's rarely mentioned outside of x86 inline assembly. I've never seen any other processor mentioned. I normally was stuck looking for examples in the linux kerne...

Re: Need Help With xgmplayer

So then now the problem is from the driver wrapper probably... Looking at the source (which are in full assembly :| ) i don't see immediate issue but of course there is many possible mistakes. Also i tried to look what is doing the Z80 and it seems that it's not even starting to play the music as t...

Re: Need Help With xgmplayer

Looking the sources file i've the feeling you're trying to read plain .xgm file. Rescomp compile .xgm into a .xgc file which is the one needed by the XGM driver. Also you need to align it on 256 bytes boundary address. Nope doing align 256 and converting to .xgc didn't work either: https://www.drop...

Need Help With xgmplayer

Wanted to give everyone an update, Sik converted the xgmplayer c code into pure assembly. However for some reason the code doesn't seem to work as the game has gone completely mute. I made a test case of the title screen, game and pause states and removed everything else. Pressing start at the title...

Assembly Language Extensions

Is there a standard set of extensions for naming your assembly source code? So far i have used .asm for Motorola 68000 Assembly Source Code. Here are some excerpts with the name removed to keep that persons name anonymous: I use .68k :P Mostly to distinguish between both CPUs .68k for 68000 asm file...

Sprite Data Mashed Up

I just finished changing the names of all my source files so they fit within dos's 8+3 limits. I did it so the code would compile with snasm68k using dosbox. http://i.imgur.com/P4UPWAw.png What is weird is no actual code was changed at all, just the paths to the file names being binary included in c...
