Re: Horizontal Scroll not showing all background image
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 ...

Re: Horizontal Scroll not showing all background image
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...

Re: Horizontal Scroll not showing all background image
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_...

Re: Horizontal Scroll not showing all background image
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 ...

Horizontal Scroll not showing all background image
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...

Re: Megadrive was always the answer
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 ...

Re: Megadrive was always the answer
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...

Re: Megadrive was always the answer
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...
