ok screw it, here's the latest on our #gameboy #homebrew project, called Leif DX! Code by me, music by my bro, art by his son. Also, this is using a sound driver to play music/sfx ripped from #lsdj, originally made by the lsdj dev, which I modified to add sfx override capabilities! :) #indiegamedev - ThreadSky

Great work on that music/sound driver.

modalmodule.bsky.social•106 days ago

Thank you! It took some work, considering it is coded in assembly, which I had little experience with prior. The rest of the game is in C using gbdk, which allows for a lot more high level coding. :)

dma-sc.bsky.social•106 days ago

Ah nice achievement even then, messing with those registers. 😉

modalmodule.bsky.social•106 days ago

Luckily I did have experience with the registers of the game boy apu having made a midi rom prior, as well as more recently a midi > gb MiSTer FPGA core. :)

dma-sc.bsky.social•106 days ago

Cool, for some nice multi systems midi jam/compos, I imagine, seeing your posts. 🙂

Music is top notch! Best of luck with the game :)

modalmodule.bsky.social•110 days ago

I'll pass the message on! Thanks!

bmoartist.bsky.social•114 days ago

This is rad. I love the music, and visuals! It seems to play really smoothly as well. I might suggest upping the deadzone a little on X just to stop the jerky camera feeling when making small movements. I can't wait to see more and how this all comes together.

modalmodule.bsky.social•113 days ago

Ya it's a tough balance to have it responsive enough to help see what's coming and yet not too jarring. Thanks for the suggestion!

bmoartist.bsky.social•113 days ago

I hear you there😅. But you know what you are doing so I am sure in the end you will strike whatever the right balance is for the experience you are trying to craft. Either way it's looking fantastic.

modalmodule.bsky.social•113 days ago

Thank you! Game feel is *very* important to me so I take it all into consideration. :)

So curious about your LSDJ compatible sound driver. Is the game and sound running off the same CPU in realtime?

modalmodule.bsky.social•78 days ago

Yep! It's all running as a normal rom/cart would. I can give more details, and I do plan to release it once I can bundle it up nicely. Right now there's some awkward dependencies and the process for preparing ripped lsdj tracks is a bit clunky. But it starts with lsdpack, a tool made by the lsdj dev

free-electon.bsky.social•73 days ago

This is really cool ... I've wanted to rewrite the music for a GBC game, but I'm hooked on the capability of LSDJ ... I've been wondering if this was all possible. Very cool

modalmodule.bsky.social•78 days ago

Which is here: https://github.com/jkotlinski/lsdpack
Then what I updated was the "player" itself (which is his sound driver), adding an sfxplayer as well, and the two have functions being called by the main file in the game project itself.

modalmodule.bsky.social•78 days ago

Now what makes it even more silly is it was originally designed for rgbds, but as I mentioned elsewhere I use gbdk, but there so happens to be a converted for .s files made by toxa (iirc) that came with hugedriver (also made for rgbds), which I happened to have and try, and if works with some tweaks

modalmodule.bsky.social•78 days ago

Converter* for rgbds flavored assembly to gbdk flavored, to clarify. Anyway, once that's run, and the resulting files are tweaked just a bit, then they're ready for compiling/assembling through the usual gbdk pipeline.

modalmodule.bsky.social•78 days ago

So in a perfect world, either my player/sfxplayer would be translated for gbdk assembly to begin with, or at least the conversion tool would be updated to accommodate this situation to avoid the manual tweaking. I know so little about assembly that this process has been my current workaround.

This is rad!

Also, this shows the next screen, with a different tileset and palette: https://bsky.app/profile/modalmodule.bsky.social/post/3lcjwlyzqis2z

So this post seems to be getting traction all of a sudden, just want to share the latest iteration with new enemy designs: https://bsky.app/profile/modalmodule.bsky.social/post/3ldfj53x6ms2p

modalmodule.bsky.social•104 days ago

I realized I didn't mention, this is being made with #gbdk! :)

modalmodule.bsky.social•114 days ago

This journey started with a gbjam game, so within game boy restrictions (DMG so 4 color only, but you could switch palettes), but made for PC. The wild notion was to "port" it to hardware, but of course there are limitations to that. Check the og here: https://modalmodule.itch.io/the-rise-of-leif

modalmodule.bsky.social•114 days ago

That said, since this is being made for game boy color, we have more colors to work with! So in some ways it's more limited, in others less! :)
