Atari Sid 5 released, 30 songs plus MADS source code

This is just great. Small request: Please add auto-disabling BASIC to the XEX. They fail to load with BASIC enabled and that's pitty for such cool code.

> inc IRQEN

Why that?Does it effectively clear the IRQ (dummy read to $FF writing $00?) bit so no new IRQ is trigger after RTI?

 

 

INC is a Read-Modify-Write instruction. It first reads a zero at bit 0, it writes a zero when it is modifying the value internally (increase by one) and then it finally writes a one to bit 0.

Isn't the INC standard?

Nevery actually used in IRQ in 30 years for something reasonabe in my code. "NMI should be enought for everyone" - Billy Gates 1985 or so, I think :-)

A little bit of shoe-horning has got Martin Galway's Hyper-Sports music and sounds into the player.

This I've put into an AtariMax 128KB image so best run under emulation using PAL at this point.

The C64 SID player routines use a fair chunk of zero-page and so that had to be catered for.

 

Overall doesn't sound too bad. There is an issue when cycling through the tunes, via console key, as one effect (a repeating click resulting in a sound like a train) doesn't get cleared for the following 3 samples.

Executable version attached... plus I liked the tape loader music used on the game too so have included those.

mixing both methods in a tracker is a cool idea emkay... that would make a lot of sense... the either or all or nothing thing really does hold things back... wouldn't it be cool to have the best of both worlds? I think you are right! A fusion of the two would really shine!
