All right, I've been trying - for long - to make a 3D engine for the 32X. I failed. Twice. At least. But there's no reason not to share a post mortem ^^ So, here is how I compute the slopes of a triangle Raster or how to draw a triangle without grDrawTriangle, a FPU, or even a DIV! Slopes O +---> x ...

Really nice work. Especially if you didn't have a MD before X-mas. Impressive !!

OB1 actualy it's because my previous code was useful to you that i decided to release this one

It indeed was!!!
Thank you very much again ^^

Biggest news being Pascal is alive and well ^^

Thanx Pascal ^^

In mathematics often you have an unique solution (or a group of) and an exact methodology to arrive to that conclusion. Frequently in life you don't have this situation, but you have to chose your own framework to reach to a misty success. (...) In most cases this is the clearly the wining solution...

It's an algorithm to split big sprites. First it loads a 4bpp bmp file. If the image size is not 8-pixels aligned, it generates the 8-pixels aligned images, with an offset on width and height, up to 49 images (7 pixels width offset x 7 pixels height offset). Then, for each 8-pixels aligned image, it...

All right. This may not be the BEST algorithm on earth to split sprites and so on. Especially, it doesn't optimize very well "holes" in sprites (an empty tile inside a sprite), but it manages to achieve some neat results. At least, good enough for me. https://www.dropbox.com/s/m3hctty54yox1mj/Street...

To do only for itself. And 5-10 SMD fans.

Here's to the crazy ones, the misfits, the rebels...

• 4 palettes for sprite + 4 palettes for BG.

Neat. 8 palettes, and no need to modify background tile or sprite entries (still 2 bits for the palette number).

I think the rest of the hardware is already perfect :p

Reading the TF530 topic (http://gendev.spritesmind.net/forum/viewtopic.php?f=13&t=2721), and just for fun, I thought about a make-a-wish / what if for the Genny. If you could have added one feature, just one, single, feature, what would have it been ? A more-evolved CPU (think about 68010 cache mode...

The freemasons have at least 10 grades.

Well, it depends. Some lodges have nearly 33, some stick to 3.

Anyway, I'm with Sik on this one.
Write stuff that brings value to other members, THIS would be our reward

Thank you very much. I've always thought this was much needed ^^

Happy birthday to us ^^
Thank you Kan'

I use the asmsh.exe to assemble my SH2 ASM files. Unfortunately, the .align directive padds with "0000" (Illegal instruction) and does not allows you to specify the padding value (.align alignment, value). So, I've written this macro : ALIGN_NOP macro .arepeat *%4/2 NOP .aendr endm Then, just call "...

Of course, of course, I know. I just wanted to drop the specs. I was thinking about Kaneda line : ... i'll like to know if a FPGA (or a SoC) version of Genny is possible ? ... In this "Retro VGS", in what I thought was related, the ARM would be idle, while the FPGA would be the actual Genesis. Not e...
