Didn't know about that game. Would probably be an easy code edit to get something close to it. 🤔

bbbbbr @bbbbbr.bsky.social · 8h

Looks like a great setup 💚

Added a rom / build for those without a 4-Player adapter.

But then it's just "Den of a single Snake".

Den of GBBoys

Checking compatibility. #GBBoy Seal of Approval earned. Even though their clocks run fast the game stays in sync due to how it uses the 4 Player adapter.

Q: Is that older GBBoy Colour with a very scratched screen actually a color console?
A: No! They just changed light grey to red!

Four GBBoy game boy clone consoles hooked up to a 4 player adapter playing Den of Snakes. The title screen for the game is showing.

Having a stack of cheap 32K carts comes in handy sometimes, I recommend it.

The closeout 32-64k ferrante carts are still for sale on ebay for $5.50-6.50. 😉 (if you have a gbxcart flasher)

bbbbbr @bbbbbr.bsky.social · 2d

Someone should make a 4-Player game small enough to copy to and run from WRAM, then you could just hot-un-plug with a single cart to get all the consoles going.

This game might be small enough without the title screen graphics, but the C code isn't easily relocatable.

Shonumi's research was very helpful in making this game.

This project required some further research into the Four Player Adapter (DMG-07) beyond Shonumi's, the findings have been merged into the pandocs page for it and are helping to improve emulator support already.

4-Player Adapter

The single, most comprehensive technical reference to Game Boy available to the public.

Den of Snakes, a new homebrew game for the Four Player #GameBoy adapter.

- Have a 4 Player adapter and play it? would love to see pix
- Find bugs or problems? let me know

It's a good place to spend time :)

My IPS mod for the #MegaDuck Super Junior Computer finally got a frame to hold the GBP Q5 display.
It also locks against the adapter PCB and creates a good tight fit ^^

Now I need to find a nice way to access the OSD without the capacitive-pads (inconvenient)

bbbbbr @bbbbbr.bsky.social · 6d

Seems like it would benefit from a GUI to draw those on the screen area instead

bbbbbr @bbbbbr.bsky.social · 7d

It's playable! 💚

Wait's over. We're about to reveal, entry by entry (and in no particular order), the final #gbcompo25 shortlist!

Those 19 games will be the ones competing for prizes and they will be ranked in the final leaderboard.

Stick around till the end of the thread… we have a special surprise for everyone!

bbbbbr @bbbbbr.bsky.social · 8d

Nice! Very crisp screen and printing results

bbbbbr @bbbbbr.bsky.social · 14d

Once the game is out I'll try to make a TTF and release it as free/public domain.

It's in the same family as (and sort of hybridized from) my earlier Canyon Racer pixel fonts (also free/public domain)

Me: Trying to finish a (rather delayed) very basic game showing how to use the Game Boy 4-player adapter

My brain: How about you make a new 8x8 pixel font just for this trivial game instead of finishing your code

...

#font #gameboy #pixelart

zoomed in screenshot showing a 26 letter 8x8 pixel art font that is white with a 1 pixel black outline. some of the font features: diagonal slants on the ascenders or descenders, diagonal notching cut out of the bottom left corners, hard-squarish upper left corners

Which piece did you eat?

Also, happy 401st birthday :)

bbbbbr @bbbbbr.bsky.social · 15d

I love how much of an eyesore this is

bbbbbr @bbbbbr.bsky.social · 16d

I hope my usb ibuffalo snes pad makes it that long. It's halfway there and has held up well. It's pretty much perfect use wise.

The D-Pad on my 8bitdo M30 is already creaking after just a few years.

bbbbbr @bbbbbr.bsky.social · 17d

If you find a version that works, let me know.

Looks like cc1 is bundled into GBStudio and there isn't a way to swap it out.

That's too bad since changing it might be a good way to determine if it was just cc1 causing the problems and if an older version (from an earlier gbdk) would fix the issue.

Following curiosity can lead to interesting places and turn out useful in ways that couldn't have been predicted (though it may take years to come to fruition). At least that's what I tell myself when down similar kinds of rabbit holes.

bbbbbr @bbbbbr.bsky.social · 18d

Great points and a good resource!

Most of this matches what we've seen/use in the gbcompo jams too. Including the number of dubious APKs that show up with total disregard for rules. Our list rules has gotten so long though.
