Phaser1 - new GTIA music engine

[Xuel]

you're right. in player was another bug. check now.

 

Perfect! Out of curiosity how do you keep tempo? Interrupts? Cycle counting? VCOUNT?

IRQ/TIMER4 step 1/23.50 s (original 1/23.40s but I change it - incorrect rounding at multiplicity - when change tempo during playing).

there is one imperfection in the counting time while hitting the drums, I think. I'll try to take care of this soon.

Wow. Can I say "wow" again? Some of the audio sounds very SID like.

 

So here's some questions.

 

1. Can this GTIA-based music play on a TIA?

 

2. If the answer to #1 is "yes", can you please offer your music to 2600 and 7800 homebrew coders? Because your music would greatly improve that chip's reputation.

 

3. How many channels are possible on the GTIA? 2 or more?

 

4. Can you use the GTIA and the POKEY at the same time like how the 7800 can use the TIA and a cartridge-based POKEY at once? [7800 Commando famously uses 6 channels between the POKEY and TIA].
