It's all fun and games until Vectorman starts double jumping on his enemies.

Improved 32X timing accuracy in BlastEm a bit and that fixed NBA Jam Tournament Edition. I think at this point the only 32X games that aren't playable are CD-based ones that need disc swapping (e.g. Fahrenheit). There are a few more with some minor graphical issues though.

Fixed what is hopefully the last SH2 core bug (at least until I write a dynarec and make a bunch of new ones) last night and now Shadow Squadron works in BlastEm

Been a little bit since I posted some BlastEm 32X progress. As of tonight, it successfully plays everyone's favorite not quite a Sonic game

Both (one of each).

Still a lot of work to make it fun, but the physics works for at least one rival, possibly more ! The behaviour is a bit harder to code than I thought 😱 (especially with fixed point)

Progress is slow but steady and we‘re getting somewhere. I hope many will support and enjoy this. It’s truly a passion project for Matt and he is determined to get all the pieces together the way he envisions without compromise. #Sega #retrogames #retrovideogames #homebrewgames #pixelart

improved it! this was kinda what I was going for first time around but the way I was pushing frames meant a lot got skipped over.

Dumb idea: port 32X Doom to the Picture Magic. The Picture Magic has a whole 32X in it, but the Mega Drive side has been replaced with something more minimal. Doom runs nearly entirely on the 32X side however, so… (the biggest problem would be procuring a Picture Magic in the first place)

BlastEm doesn't quite run 32X Doom yet, but it gets to the title screen/main menu now

and this fire effect demo

Got a couple of small 32X demos running last night after some SH2 core fixes. There's this plasma demo

the latest level update for FATAL FACTORY on STINKHEAD AND THE SEVEN DEADLY SINS

* Sega MD 3D engine update * Added partial/offscreen quad rendering - was painfull coding. Massively unrolled the line filling code for quads/triangles , 15-20% speedup. Implemented an algorithm to account for fluctuating framerate for Z forward movement - it partially works. Getting there !

It's sort of cheating, but I have first light for Sega 32X support in BlastEm. I say sort of cheating, because this demo does not use the SH-2s at all and instead just writes to the 32X VDP from the 68K. But hey, it's still progress. Should see some SH-2 code running soon

if you missed you chance to try out STINKHEAD AND THE SEVEN DEADLY SINS at Fur the More 2026, you got another chance at Furry Weekend Atlanta coming up!

Testing hardware sprites with a point based depth-test to on/off them behind polygons. I don't think it's needed for the sides but for future obstacles ? #SGDK #BlastEm

Stress test on real genesis 2 hardware + Amstrad CRT. The ship is not precomputed here (it will be but I wanted to test triangles). I optimised clipping a bit more and reduced the rom size. Synced at 30fps, fully stable (~160% cpu)

** Sega MD 3D engine update 5 ** Quads added , faster for 4 sided objects vs 2 triangles. Non-Linear Buffer + DMA reworked now faster than linear buffer + CPU blit . Its close still / interesting pros & cons. Assembly vertex calc + looping with qauds & triangle drawing in asm to save C calls.

Quick megadrive graphics test, drawing weird shapes using a distorted tilemap. (Yes, like Yoshi's island). details in followup post.

Another polished shadow/highlight effect we're using in Chords. No context and the same background as before. So spoiler free 😉 It's ironic that my Patreons pay to support the project and basically have the plot ruined for them! #segagenesis #megadrive #indiedev #gamedev #sega

Takeuchi's written a bit about Air Buster recently, including: X68000 Air Buster x.com/takeuty/stat... The X68000, FM Towns, and PC-9801 make appearances x.com/takeuty/stat... MD Air Buster was supposed to be 8M x.com/takeuty/stat...

** Sega Megadrive 3D engine day 2 ** Been playing around with Line & Triangle Drawing on the MD after thinking about doing something in 3d on the system for a while. Theres no hardware for this sort of thing on the MD so its a real optimisation game. All in C so far , 68k ASM next !!

I just saw somebody cheese the 3-2 boss in Moonwalker and I feel dumb for not thinking about it before. (stay on one side of the screen and make sure to keep kicking the two zombies so they split their bodies when they're on the other side to make it easier to jump over them)

Peripheral ID 0x0E is still one of the biggest mysteries.

To clarify, this is how it works in the original version as well. The entire platform is copied to the VDP's window plane, erased from Plane A, then Plane A scrolls up and offscreen. Then finally, the platform is copied back to plane A and the window plane is disabled.

For whatever reason in the Sonic Jam version of Sonic 3 (NOT the original) the HUD gets hidden for a moment when the platform detaches from the Death Egg. 1:09:39 youtu.be/CVZcCK0skLY?...

'Phantasy Star II' was released on the SEGA Mega Drive 37 years ago today in Japan.

'Sonic's Bonus Game' was a Flash game available on SEGA's website back in 1997, based on the SEGA Genesis special stages from 'Sonic 3D Blast'. This is some footage of it in action.

Sprite order is what determines who's in front of what, regardless of priority. All one needs to do is ensure the high priority sprite is bellow the low priority sprite while in front of a high priority tile layer. Footage from "I made you a Salad" (SHC 2019)

It's a been a long time coming... MEGADEV, a development kit for the Sega Mega CD, version 1.0 is released! ──────────────────── 🔗https://github.com/drojaazu/megadev ────────────────────

promising!

doing something, getting some M68K assembly practice in.

In Australia, many SEGA Mega Drive games would come with a fold out promotional piece for other games. This is their promotion for the original 'Sonic The Hedgehog'.

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

Play Sonic Eraser.

I just finished updating the latest version of Chords with Vic's Sega CD Fusion Driver. It's now doing both streaming PCM speech and background music and it seems pretty good if you ask me. More devs should really use this! #gamedev #indiedev #sega #segagenesis #megadrive

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
