I release a new version of my image conversion tool to make MSX2 games in screen 5 #msx #msx2 #gamedev #retrocomputing github.com/pvmm/XPM2SC5

Trying Danilo Angelo's tile editor I created this little experiment. Do you know what game this is? #msxtileforge #msx #gamedev #arcade github.com/DamnedAngel/...

We've acquired the historic game magazine Computer Entertainer. As in, we got the rights. We own the magazine. And we're putting it into the Creative Commons for anyone to use for free. Learn more: gamehistory.org/computerente...

MSXdev25 is about to happen again #msxdev #homebrew #8bit #msx www.msxdev.org/2025/07/15/m...

Latest update! #msx #msx2 #arkanoid #gamedev #homebrew #openmsx #msxgl #sdcc #8bit #msxdev

The animated "power pill" (with an "OR-colour" palette) is made of two sprites. #msx #8bit #msx2 #arkanoid #gamedev #retrogames #openMSX

By popular request, I’m now offering hardcover editions alongside the paperback version. The new edition is larger, printed with Amazon's premium ink and bound with a sturdy cover. amazon.com/dp/B0F4P5RB25

Oh god, stop the proliferation of retrocomputer groups and channels on every social network. My attention is not infinite.

#Gaurodan is out! The 2013 game has been completely redone to fit my current vision of traditional arcade game design. It's denser (more levels but less overall length), with better pacing, mechanics and a proper scoring system. Music by @gryzor87.bsky.social ♫ Info and downloads at locomalito.com

Adding stuff to the Arkanoid project: blocks and more collision angles depending on where VAUS hits the ball #msx #msx2 #arkanoid #gamedev #retro #msxgl #8bit youtu.be/9Jfnxcu_ZGM

Trying to analyse arcade Arkanoid for my new MSX2 port I bumped into this page that explains a lot already of how the game is supposed to work. Now back to fixing ball deflection #arkanoid #msx2 #arcade #gamedev #retro strategywiki.org/wiki/Arkanoi...

Some nice work! BTW, for those who like exploring old source code, #flashgame Dino Run 1 is on GitHub: github.com/pixeljam/Din... #retrodev #retrogaming #opensource #indiedev #gamedev

I updated my SCREEN5 image exporter to GIMP3 #msx #gamedev #msxdev #gimp #gimp3 #python github.com/pvmm/gimp-ms...

github.com/openMSX/open... following up on the last improvement, I created some context menus that copy sprite pattern and colours too. Yet another nail to the old debugger coffin, I hope.

Improving breakpoint management in openMSX. #openmsx #debug #msx #gamedev #emulation

I'm hosting a pixelart - "first dot to advanced technique" course from next month. The course is ten sessions every Tuesday and covers everything from 1bit to isometric and beyond. It'll be full of practical tasks and portfolio opportunities! www.d6learning.com/course/pixel...

Fixing ugly palette widget in OpenMSX. #openMSX #msx #debugging #widget #dearImgui

Basic session management is almost ready. github.com/openMSX/open... Commands: save_breakpoints, save_watchpoints, save_conditions, load_breakpoints, load_watchpoints and load_conditions all available on openMSX console. #openmsx #debug #msx #gamedev #programming #debugging

Here are the official Google Drive links for my two games. Other hosts have out of date builds, so always DL from here to ensure the latest versions. Double Dragon: Legacy (PC) shorturl.at/ZM4L0 Final Fight: Enhanced (Amiga) shorturl.at/3YBoO More info: prototron.weebly.com #GameDev #BeatEmUp

I wrote this today using a bitmap mode of the V9990 #msx #v9990 #3d youtu.be/v1Y6MWcuqAQ

I wrote a Tcl script that allows C developers to create C-aware breakpoints on OpenMSX console. You just need to compile your code with -debug to create a file with symbols and their respective addresses. It works just like gdb. github.com/openMSX/open... #msx #gamedev #msx2 #openmsx #debugger

Yet another tool that performs SDCC/OpenMSX integration. github.com/openMSX/open... #openMSX #sdcc #retrodev #msx

The Genesis and the Everdrive cartridge I purchased are finally unpacked and ready to use. Let's start programming the Genesis with the SGDK. #gameProgramming #sgdk #genesis #megadrive #homebrew

I created a simple tool that extracts data blocks from vgm and vgz files. It's WebAssembly compatible, so you can even run it online here. github.com/pvmm/vgm-dat... #vgm #vgmrips #webassembly

I've been experimenting with emscripten lately, so I created a skeleton cmake project that prepares emsdk and use it to compile C code instead of a C compiler #cmake #emscripten #webassembly github.com/pvmm/skeleto...
