*** Mega Parodius (MegaDrive) Update *** Dialing up the engine to see what it can handle and we run out of sprites before cpu so thats a good thing as we don't want any slowdown . Not accurate to arcade but might be an insane mode option, lots of logic / animations missing / WIP etc. 1/..

I just realised that scrolling can be used to do temporal reprojection of interlaced lines to reduce the artefacts. Only in 2d space but still 😮!

Chunky, but 60 fps 3d possible with colors and transparency on bare metal Megadrive #SGDK #BlastEm

Ported the #C64 sprite handler to #Amiga (bottom left, using 16blit) and to #SegaGenesis / #MegaDrive (bottom right, using low level functions from #SGDK)... Hello SEGA!

My first (mini) boss! It's simple but actually quite fun to battle. I learned a lot from programming all the different aspects. I posted a 3-part dev diary about it on my Patreon if you are curious. www.patreon.com/c/mechazone youtu.be/3oY2uPrjfxE #Gilgamech #GameDev #IndieDev #SegaGenesis #SGDK

Was analysing code performance for Mega Parodius for Sega Megadrive as I have just implemented Lazer collisions which are a major performance hog on the arcade port ( even a couple of lazers coliding with the Catboss cause slowdowns on the arcade port for example) and I found something curious...

My friend Gabriel Pryon & resident Grand Master pixel artist on Mega Parodius has made a video on the WIP to date on the port from Arcade to the Sega Megadrive and some of the challenges faced, along with comparisons to the Arcade and other ports. Thankyou Pryon !! www.youtube.com/watch?v=8W6K...

* Mega Parodius Update * New WIP: Blue Bell Explosion White Bell Explosion Catboss + Animating Trees Music updated (mark 4 - orchestral hits in) Due to 30 FPS video here on BS, please refer to YT link below ( otherwise the bomb effect is affected ) . youtu.be/ID2WfqSnyk0

Mega Wipeout incoming ;-) This is looking silky smooth !! Its interesting the potential the Megadrive has for 3D rendering and I'm excited where this goes next. This reminds me a bit of Gasekas work in the Starfox Demos which I hope more updates come also.

Love raycasters , this is looking really good with the enemy interaction going on and detail in the wall sections. Keep it coming haha.

* Mega Parodius Update * More colors ! Pyron reworked the background to 19 colors from 16 colors in the background, 3 more shades for a better gradient by using raster h/int effects. Music reworked by Vector, smaller size with more detail, includes the choirs created in FM and PSG sound. 1/2 ...

Sega Genesis Parodius Update - LAZERS !! Using a rather exotic effect here to draw the lazers using raster trickery . Otherwise 4x options and Lazers would lead to a load of sprite overload/dropout. Needs work yet to get it accurate to Arcade Lazers but I was glad to see if finally work !!

Thanks to Sega16 for covering our game - amazing stuff !!

More Scaling and Rotation fun on the Megadrive !! This is the service/menu screen for my game Lufthoheit. The 68k processor is software scaling the image in the X direction and the VDP helps to stretch the image vertically. The 68k processor is doing the rotation on the asteroids also .

** Sega Genesis S.O.T.A update ** 30 FPS video kills a few things I'd like to show here , oh well I can show this one at least . The vid shows some secret room dissolving into view and uses Shadow mode for a mid transition transparency effect. Some other bits in notes below ..

PAPRIUM CAN NOW BE PROPERLY EMULATED! THIS IS NOT A DRILL www.comunidademegadrive.com.br/2025/07/papr...

** S.O.T.A Sega Genesis Update ** I've been working on new Sprite cutting tools / middleware for Large Sprite based Objects that can be used for extra backround objects in the game. Video Below of the progress - goals and notes below 1/...

Too busy to post but this was painfull to get working , what are you looking at ? 15 colors slots used in palette 4 to get 26 colors from onscreen - see Purple and Blue Ninjas. This is a bit tricky on the MD, especially combined with 8 way scrolling and multiple splits. #SegaGenesis #SGDK

Almost finished integrating the Fusion Driver by Vic into SGDK! This will let SGDK devs fully utilise the Sega Mega CD's sound hardware using ADPCM samples, SPCM, and CDDA. Exciting times for #SegaCD #MegaDrive #Genesis #SGDK #IndieGameDev! 🎵🚀

are the rumors about >1min videos true?? I've got a lot of Sega Genesis stuff for a certain game by a certain @nosebecc.bsky.social (NSFW!!!) that a lot of people probably aren't even aware exists...... here's a cheery festival town theme, featuring what would become one of the game's leitmotifs

This week I've been working on a tilemap streamer, as you move around it loads new tiles in, so you can have million tile* maps with only a small chunk of VRAM used. Still needs optimisations. Big props to @shannonbirt.bsky.social for giving me pointers. *untested claim

Hello. Have a 5-minute sampler of snippets of a few songs from the game Chords. youtu.be/hh3p3Ks3c_A #SegaGenesis #SegaMegaDrive #Homebrew #YM2612 #SN76489 #SegaPSG #FMSynth #chiptune

* SEGA MEGADRIVE Software Scaling + Rotation * I've been tinkering with Rotating sprites in software aswell as scaling, I think it looks pretty sweet ! In the vid 4 * 32x32 sprites are rotated through 64 steps at 30 FPS on CPU. 1/..

More Megadrive Scaling madness !! Convert scaler to a line scaler rather than column, allows for per line expansion / contraction eg more like mode 7. Speed up the code & have about 50% cpu free running the scaling (cpu calculated) + sprites + audio etc. The target for this is ingame effects !!

I love those streamed tiles for the background , gives it a painted look and far more detailed and less repetitive than you normally would see on the system.

Effects time - Software Scaling on the Sega Genesis !! End goal is to use this in game - right now testing on our Game logo. Written in 68k assembly for speed. Software scaling horizontally with the VDP helping out on the vertical scaling (still takes some cpu). Now for some more optimisation !!

Bored of playing games - back to Lufthoheit Dev !! Been playing Lufthoheit in minecraft mode eg boxed sprite analysis time - Exodus supports this and its great !! Trying to reduce sprite dropout in heavy scenes ( > 20 sprites or > 320 pixels per scanline - will cause sprite dropout on MD ) ..

No4 r us !! Broke going to be us this year too once these games drop .. 😆

Very cool ! Need something like this for Megadrive. In built debugger is yummy.

More Shadow n Hightlight (S&H) goodness on Sega Megadrive. Who said 61 is the limit ? Modified tools to allow two palettes in the foreground so colors are boosted to ~ 90 colors from 30 colors (2 base palettes). Using S&H sprites acting as pixel darkeners/brighteners overlaying the forground.

Full post on the other place we wont mention, tldr version here . Busting color limits on Sega Genesis using Shadow and Highlight mode to get 45 colors out of a 15 color palette. The tooling is actually the worst issue with this technique. Always on the hunt to push things on segas finest !!
