By request from the community I've fixed a bug in Space Moguls (#C64 4 player strategy, 2018). On planet Alia Terra a cell could seem to produce a full amount of items when it actually produced none under certain circumstances.

I've implemented collision in my current #Commodore64 game project and now I have to decide if hitting something kills you or if you lose "energy" and I need to push the player vessel out of collision.
It is quite fun to do some fairly trivial math in 6502 assembler, when it all works of course....

I have written some stuff, revealing my pdt project, included some profiling graphs and some fun stories together with a few other coders on the team..
Join us tomorrow at 2PM CEST for our next All Under Heaven dev diary! We'll be giving a detailed look into how expanding Crusader Kings III to include all of Asia affects performance, and what we've done to address it.

My temporary #Commodore64 game project is looking surprisingly good. Looking forward to wrapping it up!
(still need to get started on collision though....)
I'll get back to Island Adventure soon enough :)

I worked on the orig Pac-Man World 2 and I'm really excited to see how the game was modernized in action!
My fondest memory was working on the Pookas jumping around! I also had some fun making a rope bridge, the bdoings. I did a water sim but that didn't make it so I made a fun wake effect instead.

It was a fun to assist Ancient with the modern console ports, including building a Mega Drive emulator from scratch! (I previously did the Toaplan collection for Steam/GoG)
It is almost finished now, just a few reported issues then console version release and the physical modern platform release :)

I’ve followed the development of Earthion for a while now, having played it last year, and I’m confident in saying it’s one of the best STG games ever to grace the Mega Drive… until the cart comes out, grab it on Steam and enjoy the ride!

Both super excited and nervous about the release tomorrow! Bringing this game to PC and consoles has been a lot of work but also fantastic and fun.
The port is built from scratch and Sokol.h and it reminded me of how great the mega drive hardware is. I will create something new for that!

I also play with scanlines but I like to increase the saturation quite a bit to see more of the colours in the art.
The reflection in the frame is also clearly visible in this video!

In the Game Spark preview of Earthion (www.gamespark.jp/article/2025...) they included [console port] screenshots with some visual details that I had a lot of fun creating.
There are a lot of controls to adjust these details so you can get exactly the CRT or pixel experience you want.

Now that Earthion & Toaplan are pretty much taken care of and a new company is taking care of the final stages I have been able to relax a bit and work on my own retro projects.
I have sort of started over on an older C64 project so I can greatly improve the precision of the simulation :)

Famitsu has previewed Earthion on both Mega Drive and Switch. It is an interesting perspective touching on the nostalgia, the difficulty of older games and how this game differs.
