My x86 emulator now runs ROGUE (1984). New blog post about what it takes to go from raw bytes to a playable DOS game: loading MZ executables, memory management, and interrupt handling. twied.github.io/2026/08/18/m... #x86 #retrocomputing #emulation #dos

let people be weird. I wanna see you freak out over the things that excite you over being shamed into conforming to the norms.

So here's how i'm using those pixel-art floppy disks in MartyPC. Drag a disk image onto MartyPC's window and you can drop it onto the drive you want to mount it in. #retrocomputing #emulation #martypc

Published the source mappings for the Sierra On-Line SCI Font builder. There are version 1.0.0 WOFF2 files for FONT.000 available in that repo, as well as instructions on how to compile the fonts from scratch and which games you need to have access to. Check 'em out! github.com/32bitkid/sie...

New to martypc.net - Multi-monitor support! Run CGA + MDA here: martypc.net?machine_conf... Run CGA + Hercules here: martypc.net?machine_conf...

MartyPC Web Edition

An IBM PC/XT emulator written in Rust - Now compiled for the web!

Also new for MartyPC 0.4.2: Dual-head support, in a single window. This is the same CGA card output being rendered side-by-side with unique shader instances. #retrocomputing #martypc #emulation

this is the keyboard hitbox editor for making an on-screen keyboard for MartyPC, eventually. It allows you to define rectangles of a bitmap, that can then be displaced by a fixed offset, making it look like the keys are being pushed. #retrocomputing #emulation #martypc

This might become A Thing™️

in honor of the IBM PC's 45th anniversary today, here is the original prototype motherboard! which side is your favorite?

A new upcoming feature in MartyPC 0.4.2 A new internal file-transfer API allows you to send files back and forth between the emulated system and your native OS while in DOS - no special drivers required! #emulation #retrocomputing #martypc

Happy PC Day! It's the IBM PC's 45th birthday. The Chicago Classic Computer Club (the org that runs #VCFMW) recently accepted this donation of a used IBM PC 5150 system, notable for having its original boxes and packing material (which are much more rare than the items themselves).

So @gloriouscow.bsky.social created a project to allow the PCjr's infrared keyboard to be used via a USB connection. $25 of parts from AdaFruit later, I am now able to use it as my daily driver keyboard if so desired. #pcjr www.youtube.com/watch?v=5cvi... Project info: github.com/dbalsom/pcjr...

You can form valid 8088 machine code as a MS-DOS COM executable using nothing but UTF-8 Braille characters and Windows newlines. This is what it looks like rendered with 2x4 bitmaps. You can view the actual COM file here: github.com/dbalsom/exec... #x86 #asm #assembly #8088 #retrocomputing

Not only is this a fun, addictive little game, but full assembly source is included. I checked out the 8086 source and it's very well done.

Here's a link, for anybody interested: shdon.itch.io/snake-temple Both the C64 and the DOS version are free and assembly source for both versions is available, as well as a C64 BASIC version.

Friday Blerb! youtu.be/H5heVkauR3M This disk was given to me at VCF Southwest 2026 and the idea was immediately intriguing! It's a version of 3-card Klondike Solitaire that plays on nearly any MS-DOS PC, fully contained in a 3KB binary. Small enough to be loaded entirely from a QR code!
