TI-99/4A port of Colecovision Ambigram

Daniel recently did a Colecovision VDP demo in Z80 assembly language.

You can read all about it here.

 

Yesterday I ported his Z80 code over to the TI-99/4A. Basically as a test for my spectra2 library.

I was surprised that porting the demo was so easy and straightforward. Took me about 4 hours. The biggest challenge was actually

dealing with the 16 bit registers whereas the Z80 has 8 bit registers.

You can download the cartridge binary for classic99 here.

ambigram.zip

 

And here's the TMS9900 assembly code. I tried to stay very close to the Z80 code. I'm aware that we normally do certain things differently on the TMS9900. ;)

Pretty cool. What I'd really like to see (or be a part of) is the MSX BOLD demo ported to the 99/4A. I emailed the guys who wrote it, but they were not very responsive. I guess we will just have to figure it out for ourselves... :)

 

 

This is probably a stupid question, but does the MSX use the 9918A? Those graphics do not look 9918, but I could be missing something from the YouTube encoding.

MSX1 used the 9918A

MSX2 used the 9938

MSX2xxx used the 9938, 9958, 9990, and various others

 

Some of the best games of that era come from the MSX, and the graphics are awesome. It is a shame all our software is blocky and ugly, since we know it could have looked much better. Do a Google search of MSX1 games and take a look at some screen shots. Konami games especially, they were masters at 9918A graphics.

 

Of course the MSX used the Z80@3.5MHz or faster and did not have a wait-state generator slowing down every memory operation, so they actually can over-run the VDP. Basically they can pump data to the 9918A faster than we can, so it would be interesting to see if we could pull off a demo like BOLD.

I would be interested to know if this was recorded on real MSX hardware or in emulation..

I know there was some controversy in the past in the C64 scene about limitations of real hardware VS the advantages of Emu. Any ideas ?
