Hi everyone,

I am looking at building a simple master system rom that can play Christmas songs.

All I'd really want to do is be able to somehow switch between different songs, even if its as simple as pressing button 1 which will skip to the next song. I'd also like it to display the song title and maybe some Christmas related sprites/graphics on the title screen, and/or on the screens where the song plays.

edit: To clarify (unsure if this is relevant), I'd like it to play using the SN76489 chip not the YM2413 FM Chip as I will be playing the program on an Australian Master System.

Please note I know next to nothing about SMS programming, apart from setting up all the software (context, WLA DX) and checking that it works by building a simple hello world program.

Could anyone point me in the right direction? Any suggestions would be appreciated. This might be fun!

Cheers!

First you need the songs.

You could use my VGM player but that would require using an Everdrive and picking a new ROM for each song. This has the advantage that no code is required.

Else it would be a PSGLib conversion and some custom code to pick songs. Throwing a picture on the screen is relatively simple, anything moving is much harder.

All this is doable in C instead of assembly if that helps.

Thanks for that!
I didn't know about your VGM player. It's exactly what I wanted :)

I'll play with MOD2PSG2 to create some VGM's. Then the VGM player and try it out in Meka for a start.

I know a little C (a lot more compared to assembly lol). Simple picture would do, a Christmas tree, nativity scene, things like that.

If anything I make is half-decent I will be happy to share it on here :)

The VGM player has a Christmas-ish theme and visualiser built in...
