Does anyone know if any USB gamepads exist that only have a single button and D-pad? I can only find Atari-like joysticks... (Yes, it's for my Arduboy game. 😅)

After 13 years, I finally released my game! It's a cozy narrative game with light platforming, with one cute dragon! Works great on a Steamdeck; take it on the go or play on PC! So happy. I released. Onto the next project. :'''') Link - store.steampowered.com/app/893710/ #gamedev #indiedev

Over on the Arduboy forums, I've put up a $150USD bounty for anyone who can find a safe way to switch between two different games. If anyone is able to do this, I'll finally be able to add a lot more features to my Bytes and Knights game! community.arduboy.com/t/150usd-bou...

Just released my Pebble watchface! It's a 1:1 recreation of the title screen for Pokemon Red/Blue, even with the animations! I have several color modes and even had to recreated all of the sprites in 1-bit form. 😅 Love this watch so much!

I did it! I finished programming the Pokedex for the Arduboy FX! It contains all sorts of details for each of the original 151 Pokemon, including stats, evolutions, abilities, and even footprints. Another cool feature is that you can mark each Pokemon as caught or favorited. 🫡

I finally got in the proxies I designed/printed for a Kung Pow-themed Magic: The Gathering Commander deck. I have friends who make wacky-themed decks, so I thought it would help inspire me with a starting point since I am pretty bad at MTG. The deck list is here: moxfield.com/decks/Cf6vqS...

Living in Korea has a lot of perks, like being able to attend the yearly Pokemon Town event in Seoul, each year. But, this time, there is a twist because it's themed after Ditto, and there is even a Korean-exclusive Pokemon card as part of its Metamong Project. #메타몽프로젝트

Every year, there is a rotation that happens in the Pokemon TCG, making older cards unusable in the standard format. This year, an unusually high number of my decks are becoming impossible to use as critical cards rotate out. 😥 So, I wanted to break down each one for you.

Decided to do some pixel art, today. I think a small fighting game with these kinds of sprites would be so cool. These would also translate to 1-bit pretty easily, too. #PixelArt

I am working hard to get Bytes and Knights 3.0 released as soon as I can. I overhauled the AI and also programmed 12 new cards to fill in gaps in the gameplay, allowing me to update the each NPC's deck and even make 2 new characters to play against. I'll release when I finish the card art!

Did you know that the 1998 Tiger Electronics Pokedex has unique monochrome sprites that have never been extracted? I was considering making a Pokedex app for the Arduboy and trying to dump the ROM. Would anyone use this? Or even want to help me with reverse engineering?

Happy #MEDAROTDAY2024 ! I already posted about my Korean Medabot cards, but I also found some vintage Medabots "딱지" (similar to POGS) from 1999. Because of video length restrictions, I can't post the full unboxing, so I'll just share pics of the box and 메다로트 딱지. 😀

As ya'll know, I'm a HUGE Medabots fan. Even though merchandise is impossible to find in Korea, where I live, I managed to find some Korean Medabots (메다로트) cards from 1999! Little info is online, but I think it's a translation of the JP TCG, instead of the EN TCG.
