Happy New Year 2020

Happy New Year. Here's a little fireworks demo. I didn't have time to polish it very much or compress the data, but maybe I will expand it next year.

 

The file is a 64K non-inverted cartridge image that requires 32K RAM. You can open it directly in Classic99 or https://js99er.net, or use it on hardware with the FinalGROM.

I love it, it works great on real iron, but I was not able to use it in Classic 99... what did I do wrong?

It doesn't seem to start in classic99 due to an incorrect cartridge header in the uppermost bank (which is where classic99 sets the initial cartridge bank.)  This is what's in the lowest-bank cartridge header:

00000000  aa 01 01 00 00 00 60 0c  00 00 00 00 00 00 60 38  |......`.......`8|
00000010  09 46 49 52 45 57 4f 52  4b 53 58 58 58 58 58 58  |.FIREWORKSXXXXXX|

Here's the uppermost bank:

0000e000  01 01 00 00 00 60 0c 00  00 00 00 00 00 60 38 09  |.....`.......`8.|
0000e010  46 49 52 45 57 4f 52 4b  53 58 58 58 58 58 58 58  |FIREWORKSXXXXXXX|

Looks like it got shifted by one byte.  Other banks are affected similarly, or are missing the header altogether.

Okay, glad it was not something I did.

Very nice.

This version has been fixed to work with Classic99.
