Converting PAL to NTSC
I've got some PSID files that are absolutely perfect for a demo I'm working on, but they are PAL and the demo is NTSC. What steps do I need to take to convert the SID data to NTSC so that it plays correctly?

hack the player code and
- make it play 20% slower (in case you are planning to play it from a raster irq)
- recalculate frequency tables for ntsc

Are there any good references for what the frequency tables look like? Am I better off loading the SID in a tracker and manually editing each not, or trying to write a program to automatically recalculate each note?

and by hacking the player i mean just that - load it and edit it in ml monitor. |
