Rapmaster 'ToeJam & Earl' SEGA Mega Drive

Sega should have released Doki Doki Penguin Land MD on cartridge.

background testing

there's also a lot of edge case hunting, like making sure the kill-screen isn't broken by raster interrupts. Realised earlier that the curtain drop is affected by the water palette switch, so I had to go make it sneakily push the waterline offscreen as it scrolls.

Comparison of Axel's selection, across the SEGA Mega Drive, Master System and Game Gear versions of 'Streets Of Rage'.

This feature was late for the Razing Core demo but I've now added more background destruction for scoring, and it's just fun to destroy things! #mastersystem #homebrew

モータルコンバット3は海外だけの発売だがBGMもなく用意されている難易度もむかしく滅茶苦茶ゲームバランス崩壊しているのだが何とか攻略したい

Some of Atsushi Seimiya's works as a graphic designer during the Mega Drive era: 1) Blaze from Streets of Rage 1 2) the main character on the title screen of Cyber Police ESWAT 3) a background for the ending of Strider 4) the background of the level 5-1 of Revenge of Shinobi (with his signature)

Mega Parodius (Megadrive) Scaling !! Went crazy, decided to do the hardest bit (possibly) in the port next , Stage 8 Boss !! Horizontal scaling only at present , vertical is next . Horizontal is much harder to achieve at speed. 1,2,3,4x scale over 74 updates. He's 21kb of tiles ie massive !!

I made these tortle guys more fun to play around with/bully, they're designed to be docile and only lunge if you annoy them. (Spindash sprite stolen from Sonic Advance - placeholder) #gamedev #sgdk

More pics: www.fromjapan.co.jp/japan/fr/auc... I suppose several CD-ROMs were produced for this machine.

This is the first time I have seen this cartridge, designed for the Linguaphone Education Gear, the Japanese version of the Multi-Mega/CD-X. xcancel.com/mega_dra/sta... auctions.yahoo.co.jp/category/lis...

that's more like it!

*** Mega Parodius Update ( Sega Megadrive ) *** For 60 FPS video I've posted the update on YT below link below. But just quickly - more in the description in the vid , updates on the Blue Bell explosion , Enemy destruction / collisions & VRAM handling !! www.youtube.com/watch?v=pq_I...

It's also reasonably smart, if a BGA/BGB are sharing a palette, or an enemy/prop uses one of those or the player line, or you need a particular layout for s/h mode, it shuffles stuff around and can give 2 entity lines instead of just 1. screw you sega for only building this with 4 palette lines!

The benefit is I can throw a map together with any old props & enemies already built without having to tailor anything specifically for it. Just added mr snuggles (temp name) to my cave map without any prep work, just spawned and worked. Will open source this part as it's useful™

Rewrote my palette handler, so now the game has 1 or 2 free lines going, it doles them out to active entities that request it. See green monster in pic 1; neutral position far from any props in 2; playing with a see-saw in 3; #gamedev #sgdk

Level-up flourish

The #homebrew project, "G-Zero" by "gasega68k" recently received an update The original demo already served as an impressive tech showcase, replicating the #SNES' iconic Mode-7 3D effect, but on the #Sega #Genesis Get it here: gasega68k.itch.io/g-zero #retro #retrgaming #gaming #gamedev #indiedev

It was a long road of learning and experimenting, but I have finally completed the first real boss for my #SegaGenesis and #MegaDrive game, #Gilgamech There have been a lot of enhancements since my last video. Check it out! youtu.be/Bzd8JaX5B94 #IndieGame #SoloDev #SGDK

SMSRally, Day 17. Worked on improving the world to pixel to screen space transformations. The car follows the ground better now. Sprite still glitchy at certain angles. #sega #mastersystem #homebrew #devkitsms #gslib

Machinery 'Pengo' SEGA Mega Drive

(cute) pest control

Took a quick look at Body Count and looks like they changed the Sega Mouse with the Mega Mouse, as expected from the region (yes, US mouse is "Mega" and non-US mouse is "Sega", they got it backwards). Also that's definitely Not Bruce Willis™.

This is going to go underreported but Garfield The Lost Levels replaces the password and bonus round options with one that lets you watch several of Garfield's animations.

I was wondering what were the changes in the Sega Channel version of Bloodshot (er, Battle Frenzy) and it didn't take long to find.

Congrats to Sly Dawg

So the Sega Channel guide in Argentina and Chile was bilingual, huh? (I assumed it'd stick to one language, not offer both)

The SEGA Mega CD was released 34 years ago today in Japan.

We've just updated our Steam beta version! You can read a detailed change log on the Steam news! 👇(･ω･)🤙 store.steampowered.com/news/app/370...

Not on Patreon? I uploaded a video of my new Crab Boss to YouTube. It's still in development and needs a lot of work on the attacks and timing, but most of the parts are in place and working. youtu.be/JR4D5raqw2Q?... #SegaGenesis #MegaDrive #GameDev #IndieGame #SGDK #Gilgamech

We've finally finished supporting Horizontal Blank callbacks!! Changing the palette mid-frame is now possible!! ᕕ( ᐛ )ᕗ💦 #megadrive #mdengine #homebrew #indiedev #gamedev #sgdk #pixelart

Imagine trying to sell Sonic 3D in your product but you accidentally include the 819 prototype in it.

We finally finished MD Engine trailer!! You can watch it here ( ˘▽˘)っ www.youtube.com/watch?v=0A1o... #MDEngine #megadrive #genesis #sgdk #gamedev #indiedev

'The Revenge of Shinobi' was released on the SEGA Mega Drive 36 years ago today in Japan.

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 😮!

Flipping Out 'Thunder Fox' SEGA Mega Drive

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!

had the smart idea to use a bunch of sprites up like this, virtually free as far as performance goes because the screen-space coordinates for the corners are already figured out.

Bit more work needed before it's really a complete game, but this is coming together nicely. I massively sped the line code up, actually surprised it can hit 30fps with all these things littering the stage without having to use any assembly. #sgdk #gamedev

Unreleased "System Pack" extension to the Sega SC-3000 computer, and a prototype of the SF-7000 super control station disk drive (spotted in a recently scanned 1984 issue of ASCII magazine) www.smspower.org/forums/20690...

I stuck her in a marble just to see what would happen! (minigame WIP)

Woosh! 'Lawnmower Man' SEGA Mega Drive

NOT the last one, that's for sure.

little megadrive experiment

So it is possible to do 60fps 3d on the sega megadrive by using a very exotic indexing method to simulate 2 colors + alternating lines + fast DMA. Totally interlaced my brain 🙃

Scamp is outraged as per usual... #segamegadrive #segagenesis #chords #indiedev #gamedev
