Two Black Cats @twoblackcats.jp · 15/09/2026

Hopefully, I get the last few materials for MD Engine patch 1.0.7 soon! I wanna rest for a day or two testing our Game Gear WIFI cart :D! #gamegear #mdengine

Two Black Cats @twoblackcats.jp · 04/09/2026

We've now added a CRT shader to the preview of the game so you can get a more retro feel! Don't forget MD Engine releases on Sept. 7th! #mdengine #sgdk #megadrive

Two Black Cats @twoblackcats.jp · 15/08/2026

We've finished the #Playtiles integration with #MDEngine, so you can debug directly on your phone if you have a Playtiles Devkit. It will be available in the release! @playtiles.bsky.social

Two Black Cats @twoblackcats.jp · 04/05/2026

We've spent the last few weeks working on compiler optimization passes! We now have common subexpression elimination, loop-invariant code motion, script deduplication & script inlining! It took a long time, but with these, we pushed Solid-State Soldier to 60 FPS! #megadrive #mdengine

Two Black Cats @twoblackcats.jp · 19/03/2026

We are finishing the Android export! We've been testing it on Retroid Pocket 3 and so far so good! ( •̀ᴗ•́ )🎮 #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 14/03/2026

We finally finished our last major feature, the real-time CPU profiler! If you are like us, you can now see how your rushed script affects game performance in real time and fix it! (ಠ‿ಠ)📉 #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 10/03/2026

We finally finished the last major feature we wanted!! Event debugging & stepping!!! Now you can stop and review execution at specific moments! With the help of detached code, debugging is much easier now! ( •̀_•́ )🔍💻 #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

1144

Two Black Cats @twoblackcats.jp · 09/03/2026

We finished the event, script & text search! Now, you search for a specific event or text, and it will show you where it has been used to help with refactors! ( •̀ ω •́ )🔍 #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 03/03/2026

We finished integrating the ROM usage stats! Now, you can see your assets make the ROM bigger and bigger with each game iteration! ( . •́ _ʖ •̀ .) #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 02/03/2026

We can finally show our secret feature! We've been working on a tracker that will be shipped with MD Engine! ヾ(´〇`)ﾉ♪♪♪ It won't be as powerful as Deflemask or Furnace, but it should be capable of doing music composition for most cases! #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

3156

Two Black Cats @twoblackcats.jp · 28/02/2026

We finished script window detach support! ヽ(・∀・)ﾉ Now you can take advantage of two monitors to script while checking the scene!! #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 21/02/2026

We finally had time to advance on the design and printing tests for our first release! The bundle of Square Brothers and Inkventure! We just need to finish the stickers and such freebies! (◕‿◕✿) #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 17/02/2026

We are finally done with the first two types of slopes!! (;´༎ຶٹ༎ຶ`)(;´༎ຶٹ༎ຶ`) This covers the initial batch, we will be adding more slowly haha. Next would be adding MDSDRV support! #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

1245

Two Black Cats @twoblackcats.jp · 14/02/2026

We finally finished the plugin support! The idea is, you write some basic C or ASM code, create the event JS file, and it gets called normally! It took a lot of adjustments to properly support it, so hopefully people use it haha! ლ(¯ロ¯"ლ) #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

1156

Two Black Cats @twoblackcats.jp · 12/02/2026

We have been making some progress with slopes! Drawing and exporting are finished! Next would be actual collisions (;´༎ຶٹ༎ຶ`) #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

1164

Two Black Cats @twoblackcats.jp · 11/02/2026

We finally finished integrating the collision gridding system into MD Engine! It was designed by the awesome @shannonbirt.bsky.social! It helps boost performance tremendously for our current shooter examples! It is also highly configurable! #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk

Two Black Cats @twoblackcats.jp · 06/02/2026

We've been working on the Linux native export! We're almost done integrating everything into MD Engine to allow exporting native Linux versions of the games! (　･ω･)☞ Tested on Kubuntu & Mint so far! #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk #pixelart

Two Black Cats @twoblackcats.jp · 04/02/2026

We finally finished the last text mode we wanted to do! It loads a few of the extended ASCII characters into the VDP to be able to draw most EFIGS language words! (´･ᴗ･ ` ) #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk #pixelart

0228

Two Black Cats @twoblackcats.jp · 11/12/2025

Two Black Cats @twoblackcats.jp · 25/10/2025

We're finally on the third level layout on Solid-State Soldier. It's been quite time consuming to do all enemy spawn setup... #megadrive #mdengine #gamedev #homebrew

0124

Two Black Cats @twoblackcats.jp · 24/10/2025

We finally finished parallax + streaming support for MD Engine!!! (∩` ﾛ ´)⊃━炎炎炎炎炎 #megadrive #mdengine #gamedev #indiedev #sgdk #homebrew

Two Black Cats @twoblackcats.jp · 15/09/2025

We added a new enemy type to Solid-State Soldier! (メ°皿°)ﾉ After this quick break, back to writing docs (T_T)...

152

Two Black Cats @twoblackcats.jp · 12/09/2025

We finished Solid-State Soldier enemy shooting! (∩` ﾛ ´)⊃━炎炎炎炎炎 We still have to fix Z-ordering though...

041

Two Black Cats @twoblackcats.jp · 10/09/2025

We took a break from MD Engine map editor to work on Solid-State Soldier level selector! Soon we will have new pictures of MD Engine map editor! Stay tuned ( ͡° ͜ʖ ͡°)！

092

Two Black Cats @twoblackcats.jp · 29/08/2025

We are almost done with Solid-State Soldier levels! We fixed some of the enemy AIs as well. Soon we'll have to go back to documentation writing (T_T)...

031

Two Black Cats @twoblackcats.jp · 12/08/2025

It took some time, but we finally managed to get MD Engine working on Linux! (✯◡✯) #sgdk #megadrive #mdengine

2104

Two Black Cats @twoblackcats.jp · 02/08/2025

We finished the camera module sample! It's based on @haxeflixel.bsky.social FlxCamera example. It displays all basic options of the camera module! Follow, lerp, offset, shake, and flash. You can also set your own deadzone for better customization! ٩(｡•́‿•̀｡)۶ #sgdk #megadrive #mdengine

183

Two Black Cats @twoblackcats.jp · 01/08/2025

We added support to define animation speed per sprite, per animation, or frame! We also added animation preview support. Everything already works in-game as well! ヽ(*⌒▽⌒*)ﾉ #sgdk #megadrive #mdengine

165

Two Black Cats @twoblackcats.jp · 25/07/2025

We finally finished the scroll debug overlay! Now you can track the visible area of the game no matter your scroll setup, full screen, tile, or line! We just have to add a button to turn it on/off haha. ٩(｡•́‿•̀｡)۶ #sgdk #megadrive #mdengine

162

Two Black Cats @twoblackcats.jp · 23/07/2025

We added three debugging planes you can enable on the layers tab. They allow the display of triggers, sprite collision boxes, and temporary triggers. It was a pain to debug the temporary triggers' position otherwise... ~(>_<~) #sgdk #megadrive #mdengine

142

Two Black Cats @twoblackcats.jp · 23/07/2025

We added support to preview both sound effects & music files inside the editor! It works for both WAV and VGM files! In theory, it should also work for Game Gear and Master System VGM files too! (ˇ▽ˇ)ノ♪♬♫ #sgdk #megadrive #mdengine

261

Two Black Cats @twoblackcats.jp · 21/07/2025

We added a way to reshape the VDP at the start/end of scenes. You can have very detailed backgrounds on some scenes, and big sprites on others! In this video, we switch from a detailed background to a big sprite in the next scene! ヾ(´〇`)ﾉ♪♪♪ #sgdk #megadrive #mdengine

121

Two Black Cats @twoblackcats.jp · 19/07/2025

We reworked the collision system this week! We added a new "simple" mode that allows for up to 25 different enemies with physics + yourself at the same time! Those enemies can kick you as well! (=O*_*)=O #sgdk #megadrive #mdengine

184

Two Black Cats @twoblackcats.jp · 15/07/2025

We took a small break from MD Engine documentation to work on a rail shooter, Solid-State Soldier, for a few days! Writing documentation is sooo boring ( ╥ω╥ ). At least we fixed some collision issues while working on this!

053

Two Black Cats @twoblackcats.jp · 10/07/2025

We finally finished the localization system! You can swap between different languages on the fly with minimal game-code changes! #sgdk #megadrive #mdengine

162

Two Black Cats @twoblackcats.jp · 13/06/2025

We finally received the first batch of PCBs we're using for testing and development, now with custom logos! They support 8MB without the need for a mapper. You can save to the flash memory directly if you use MD Engine! They are based on doragasu FlatMap64 :)!
