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.

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.
