Neither. It logs every VDP write as it happens (since the bus is exposed on the cart slot) and keeps the old value of each changed byte once a second, so rewinding is just undoing those changes.

Yeah I already have a musician lined up to give it that late 80s/early 90s techno/rave/breakbeat kinda music.

I am considering doing an upgraded version of my Neon Gyre for the #NeoGeo console. Any interest in a high powered Tempest 2000 inspired shooter for the Neo? Will support joystick and of course the rotary controller. This is gameplay video of the latest Master System build

PicoPak for #MasterSystem gets REWIND! World's first real hardware Rewind in a flashcart. No one else does it anywhere for any console. Give this a like and repost if you want to see this same thing brought to the PCEngine and TurboGrafx16.

Announcing Neon Gyre 88 for the Sega #MasterSystem. It's a tribute to Tempest and exclusively playable on the upcoming SMS PicoPak flashcart leveraging it's coprocessor enhancement. Will be available for free to download with dev docs. This is a WIP with placeholder music.

PicoPak for #MasterSystem also has a built in VGM music player with visualizers. It's always annoyed me that more flashcarts don't bother with this or required kinda crappy thirdparty roms to do it. Not so with PicoPak! It's built right in. And it's damn good.

R U A FILTHY CHEATER?? Well, with PicoPak for the #MasterSystem you can totally cheat and not even break a sweat. And it saves the cheats to a text file on the sd card so next time they are memorized for your convenience. Level up ur cheatin' with PicoPak for Master System!

I hope your Sega Master System is ready. PicoPak is coming. #MasterSystem In this first look video, I talk about my save state implementation. Lots more later on as there is a hell of a lot to cover. This is just the tip of the iceberg. RETROFROG DOES.

Just grabbed Razing core by @badcomputer.bsky.social Awesome shmup for the SMS! I am completely blown away by what indie devs have squeezed out of the Master System.

Well, I've spent time writing custom diagnostic tools and have done EVEN MORE testing. Situation isn't as dire as I initially thought, but there are still problems. Read more here: dreamcast-talk.com/forum/viewto...

PicoPak for #Colecovision now has Joystick as paddle for the #MSX Arkanoid. Normally it only supports keyboard and the Vaus paddle controller so I replicated the paddle controls and mapped them over to the joystick and provided a menu option to toggle it.

In my pursuit of making the very best #Colecovision flashcart on the market, here is a new update video. QOL improvements, fixes and enhancement especially to the #MSX experience (in game menu with cpu turbo option, low latency enhancements and etc) www.youtube.com/watch?v=h-lC...

It’s hard to find good info on it, but how does the Chameleon deal with games with SCC audio? I’m still experimenting with a couple different options

Todd Gill - Retro Frog @retrofrog.bsky.social · 17/09/2026

right now I have a history tab to show the last 10 played games, but i haven't implemented favorites yet as i wasn't sure about demand

Todd Gill - Retro Frog @retrofrog.bsky.social · 17/09/2026

I know about the Chameleon cartridge, but I'm not familiar with how good their implementation is. Plus I think they have some issues running larger games. My cart supports all Colecovision games including Wizard of Wor and MSX1 games up to 1MB.

Have a #Colecovision and Super Game Module? With #PicoPak you can also now play all the wonderful MSX1 games. All the #MSX AY audio is reproduced faithfully by the AY chip in the SGM. Your Colecovision game library just got a lot bigger! SCC Audio is still a work in progress.

for SG-1000, emulating the CPU and part of the VDP. For MSX (and others) it will likely be similar.

SG-1000 games now work on the #Colecovision thanks to PicoPak CV. No conversions required. Will add support to run Sord M5 games (along with a couple other similar spec hardware) and finally MSX 1 games with an attached Super Game Module. PicoPak is gonna be 🔥

I decided to build something for about 50 people on the planet, maybe less... www.amigalove.com/viewtopic.ph... It's a chess variant game on the C128 in GEOS. Yes. You read that right. And if you are one of ~10 people that has a SuperCPU 128? It'll be about 10x a better engine (2mhz vs 20mhz).

Photo of my C128's A1902 CRT monitor displaying my game "Chess Attack 128" which is a chess game on a small 6x6 chess board where each game you and your opponent get a whole new assortment of pieces, mirrored.

Closeup of the right-panel of Chess Attack 128 where I'm currently displaying your system's stats (mainly for testing purposes but I might keep some of it, as it's kinda cool).

Comparison of the original Chess Attack chess pieces I designed, and the updates I needed to make when I switched from vector art to blocky 16x16 (later scaled up to 24x24) pieces.
