Hey, I frequently get this error when I compile. Could someone help me understand what this error is? It happens sometimes when I try to compile. When I see it, I just recompile until the build completes successfully.

error message:

2 [main] ? (684) C:\sgdk\bin\make.exe: *** fatal error - C:\sgdk ...

I wasn't thinking about the available genesis ram. I think it would be better for me to build a method to update the map as I scroll...I may have more questions on this later. Thanks for the help.

Should I be able to use an image that is 256 x 256 tiles with VDP_setMapEx()? I'm trying to see if it's even possible to use a 256 x 256 tile image, then use VDP_setMap to update the map as the player moves through it. I'm having trouble getting this to work, and wanted to see if it's even possible.

I'm using an image to display a background for a level, and I use rescomp to compile the image. I want to be able to track certain blocks in the image to use for collision detection. The image struct already has the tilemap data. So my question is, can I reuse that data to track where collision ...

I didn't know about the VDP debug with Gens/GensKMod. That helped me to figure out what the issue was, which was that I wasn't optimizing the tiles being loaded, and was loading way too many tiles.

I was able to resolve the issue by fixing my images and tilesets. Thanks!

Hi, I'm having trouble understanding how to load tilesets properly for multiple images to use with different levels. I want to load two images to use for the APLAN and BPLAN for one level. Then change to another level using different images for the APLAN and BPLAN. When I load the tilesets in the ...

I was able to resolve the issue. It is unrelated to the area of code I posted above. The issue in my code was with how I was loading the background image for a level. Here is the code:


Image *bgImage = unpackImage(&ImageFile, bgImage);

VDP_drawImageEx(APLAN, &ImageFile, TILE_ATTR_FULL(PAL1 ...

Thank you for the help. I obviously do not have a good understanding of how memory allocation works. I will go back and fix my code.

In terms of using an Object wrapper around the Sprite. I'm using the Object position X and Y to track where the object is in an area, and the Sprite positions to ...

It's very likely that I'm not using Sprites correctly. Here is a general idea of how I'm updating sprites:


typedef struct Object
{
Sprite* sprite; // Points to the sprite used in the Sprite List passed to SPR_update()

fix32 posX;
fix32 posY;

void (*updateFunction)(struct Object* obj ...

All my code is in C. I do allocate memory for certain objects. I allocate memory for an object struct, sprites, and background images. Could the error be caused from allocating memory? I'm able to run the rom on an emulator, and it looks like the sprites and images are loaded correctly. So I didn't ...

Hi, I've run into an issue with a game I'm developing. I use Kega Fusion as an emulator to test out my rom, and I'm able to load and play through the rom on Kega Fusion. When I try running the rom on hardware (using a Sega Nomad), it immediately gives me an address error. I've tried fixing the ...

I don't know enough about genesis development to understand if I should be breaking up my methods into small methods. I already break up my methods so as not to copy code in different methods. However, will having a lot of small methods slow down performance?

Hi, I'm having some trouble getting transparency to work. I use a program called IrfanView to set the transparency color on my sprites and background images. However, transparency works only when I set the first color in my palette as the transparency color. Is this how transparency works?

Are you recreating StarCraft for the sega genesis?
