I'm fighting with scroll code again, it's working but there is a small problem 320x224px, horizontal scroll from right to left, using an image with size 1024x224px The problem is that I can see when tiles are being updated, just when left tile colum is going to dissapear at the left part, it's updat...

Nice project, can't wait to see bosses

If scrolling is still troubling you, I've altered the SGDK's "Sprite" example to do basic scrolling. (see attachment, scrolling.zip) Made the playfield wider (1280px wide) to see the effect. Also, removed the BEST compression for the tilemaps, as VDP_setMapEx is slower when decompressing data (too ...

Still having problems with scroll. Let's work simple. Horizontal scroll only (from left to right). 320x224px. Only 1 plane. No sprites. I'm using sonic background from SGDK sample folder but I add px position (see background's bottom) scroll_v3.png As you can see this image have 640x224px, then 80x2...

Hi there, here testing sprite collision flag also :mrgreen: It's working, but not sure why... this is my code [..] //include and all these stuff int a = 0; main() { [...] //add sprites, pals,... and these things while(1) { handleInput(); check_collision(); SPR_update(); VDP_waitVSync(); } } check_co...

Awesome, best explanation ever!!

Thanks a lot, I will try again, have a nice day

Hi again, I'm afraid I saw lot of threads but no success at all. Ok so by default with SGDK we have 512 pixels wide, that is, 64 tiles (from 0 to 63). Question. bga.png is 640px wide. Where are the last 640-512=128px (16 tiles)? (from 64 to 79) Are they still in memory somewhere? I tried to use VDP_...

Try with another NONE name, img_file, compression, mapopt IMAGE bgb_image "gfx/bgb.png" NONE NONE IMAGE bga_image "gfx/bga.png" NONE NONE This is not working properly, lot of artifacts. The tilemap is 512px wide. You need to draw in new tiles on the sides as you scroll it. Yes, I think this is the ...

This is my .res

IMAGE bgb_image "gfx/bgb.png" NONE
IMAGE bga_image "gfx/bga.png" NONE

Tried also

IMAGE bgb_image "gfx/bgb.png" BEST
IMAGE bga_image "gfx/bga.png" BEST

No changes at all

I'm learning about scrolling, just made some simple scrolls and found that not all background images are showing at all. Just using files bga.png and bgb.png from Sample/Sprite example (both 640px wide). I write px in bga.png to check where is cut, and happens around 500px (pls see attached). I thin...

I really like the 2 MD idea. Won't it be possible to use a slave MD like did with the MCD ? Is it possible to have a "slave cart" on the slave MD with all the logic and send message to the slave ? I don't remember of the MD/MCD sync is done but something similar will be needed ... Even more, could ...

Why make the slave soundless? Mix it with the other MD either via the video mixing section, or using the audio in lines on the cart of the master MD. Two YM2612/PSG would be VERY helpful for games. At the moment FPGAs and Yamahas are not friends. If cost are to be keep as low as possible, avoid ext...

Main idea is 2 megadrives, as simple as possible, to start programming with actual resources and be able to make new games asap. This is just a theoretical exercise, I don't have any target price, it's a funny thing design theorical-but-possible new megadrive expansion, just as we did when were chil...
