Thanks ^^ but what is a VWF routine?
Christuserloeser> No I'm not interested sorry ^^ althrough this project is impressive

Yep thank you ^^
It's a virtual bitmap (like used in 3D games) done by mapping every cell on the map to a unique tile in VRAM. Then when writing a letter I find the right tile to write to.
In fact here is more precisely how it works. The map (38x32) is defined like this:
0 32 64
1 33 65
2 34 66
3 35 ...

Hello!
I don't know if this was already done before (probably :P), but here is a small text reader that I did for the Mega Drive. The goal was to experiment software writes to the VDP with a simple app.

It has smooth scrolling, and you can ...

Biggest problem is that in order to avoid artifacts you need to turn the display off during HBLANK and the only way to do that and still have enough time to DMA 8 colors is to poll the status register for HBLANK. HINTs occur too late. So you basically end up burning 100% of your CPU time on the ...

Wow, extremely impressive
Continue like this, that's really an excellent project!
I've tried to understand your wavplay demo but it's not very easy. Respect!

Sorry for the late reply :(
In fact I'm not sure I see what you mean; but if I did, with this you can have 16 colors per 16 pixels, but you still aren't free to select them; in fact every tile's first and second row use the first palette.
So let's say pixel (1, 0) wants to use color #6 (located in ...

Wow, impressive video! :o
I'm not sure I understood your explanation, but my lack of knowledge about the MD hardware combined with my rather bad english is probably the reason ;)
I'm using a single plane (B) and 4 palettes, the palette is selected individually for each tile. The plane A is used for ...

Thank you for your answer :D
Neuquant... interesting :)
I've been searching for software to convert a true color image to a set of palettes (here: 4), each tile only being able to use one palette, but found none. So I wrote mine, it was very hard and certainly doesn't give an optimal result :? I ...

Hello,
I know this demo is probably something you have already seen 10 times or more, but I still wanted to post it ^^
That's my first program ever for genesis, I wanted to try using the wonderful devkit from the no less wonderful Stef :)
