Back To The Game Boy!


Taking a break from the NES to crack on with a lil idea that formed in my head on friday night. Simple game but with a lot of possibilities



Going to look further into music generation on the gameboy in C to get something proper playing in the background.

Flaphappy will still come to completion some time.

Hurray! New project!!
Good luck.

Thanks Jay, ASM was just getting me down so going back to something nice and...well.. human, like C makes things so much quicker to develop in.

That looks great, but seems a bit buggy

My GBAsp has a Tetris D.X. cart permanently attached.
...
Mum "borrowed" it a long long time ago.

I haven’t seen it in quite a while.

I do hope it's still around, somewhere.. hmmm...

Writing up a proper convertor from Deflemask into GBDK currently. That way, actual chiptune music is possible!

Awesome! Can’t wait to hear the results

Thankfully it comes with a bunch of chip tunes in there for me to test against, so I'll have a good idea when I get close to 1:1

Got the tones out from the files now 'n' stuff, might be able to push a demo ROM out this weekend!

Woo! It plays something resembling music!

refreshgames.co.uk/deflemaskgbdk.gb

Need to add instruments & effects next.

I won't get 1:1 in terms of tempo as I'm opting to use a 60Hz loop to keep CPU usage down. Also, GBDK

Slightly more accurate Wave channel handling added tonight. Sounds much better already!

Awesome!!! Hopefully you can keep that speed up and running once the game starts to get a little busier!

Yeah, so far it weighs in at a hefty 10kb but only takes 5-10% of the cpu. Gotta add more instrument support and possibly a couple more effects. Then it's data compression time!

compressed it down to just under 7k now. that's for ~1 minute of music.

Right, noting this down for myself for later on.

Use a UINT16 array for instrument change indexes, with a linked UINT8 array for instrument indexes

keep the change indexes numerically ordered, then use a single check per cahnel to see if I need to switch instrument.

Perhaps use the same priniciple for note effects.

Compression yo!

Any way for us mere mortals to listen to your tunage?

BGB is a great emulator for gameboy. Best to run the rom through that I think.

There should be some ROM links up on this post also.

Got a bit of compression involved last night, down to 6.6kb from ~10kb before with only a little fideltiy lost in the wave channel.

Tonight... more compression! <5kb or even 4kb would be ace!

Woo! Sadly it looks like ~6k is going to be the limit without things getting really complicated.

I'm tempted to see how far down the compression rabbit hole I can go though.

Ohhh, think I've found a way to save like 2kb of data. But the playing code has to be rewritten pretty much from scratch... Aaand I'll reclaim some of that data back through code addition. Only one way to find out I guess! Still, that's gotta be pretty good going. Once I get it going!

Yup, down to 4k, still some player code to be rewritten. then sorting it out to reference different songs will be the last...yeah. the last thing to do, holy crepe!
