MS-DOS Devblog 0: The What and the Why

Blogpost link

Resubmitting as it seems like you can't both submit a link and put body text on old Reddit :')

Previous description:

> Now, this is a mess of a post, but I got inspired by posters like u/mightykin and u/Swing-Dancing-Dragon in another thread who wanted to see more bloggy stuff about bizarre bullshit. I dusted off a blogpost I was drafting a couple months ago and finished it tonight. In this case, it's an intro post about my design thoughts and tech stack developing a game for MS-DOS (mostly just about MS-DOS tech and how the stack works, rather than about the game itself, but I figure the stack would be interesting as well). Would be glad to hear your weeping and gnashing of teeth.

> No intelligence, artificial or otherwise, was used in constructing this post, and I am promoting nothing.

A relatively short (~4.5k) post about what I've decided to spend some time on, and how I got MS-DOS to comply

OWL FLY III is now in development

The third generation of our 8086 combat flight sim has left the runway - forked from the finished OWL FLY II. We went through the feedback you sent us after the OWL FLY II release, and the request that came up most was support for the different displays of the era — so that is exactly where development began, and it is already flying: the game opens with a SELECT VIDEO SYSTEM menu, quizzes the actual hardware, and offers only what the machine really owns:

Hercules - 720×348 monochrome, the 6845 programmed by hand

CGA - 320×200, the classic cyan/magenta palette

EGA - 320×200 and 640×350, sixteen colours

MCGA - 320×200, 256 colours (colors? :) )

VGA - 320×200 in 256 colours, or 640×480 in 16 colours.

On every retro card the cockpit isn't a downscaled conversion - it is its own drawn artwork, redrawn the way 1988 drew instrument panels. Playable in the browser right now:

- HERCULES (monochrome): https://kirindenis.github.io/wire-city-2/owlfly3h.html

GBC Mystery Labyrinth (Roguelike) work in progress! 'Mara's Abyss'

Let me know your thoughts and critiques. It's made with gbdk and C. All art by me. The game has been starting to become fun, and the overworld load times are finally under control (all loading is around 3 seconds maximum now). The framiness in recording I think is because I'm on an ancient thinkpad with chrome open while testing.

Working features not shown: recall to town/back, leveling up stats/spells (several per class) conversations (npc/merchants) big bosses, a companion, re-playable seeds, short story/intro. Tested on my gba sp as well. I'm a fan of dungeon crawl stone soup, fatal labyrinth, and shiren- so those have been my inspirations on this project.

Hope to add soon: fully modular item generation (suffixes etc), main quest:craft super items from boss drops for endgame dungeon, endgame dungeon.

Tooling

For those wondering what kind of tool I used for the pixelart: EXCEL!!!
There's a macro in there that exports the picture into three linked BASIC programs, that once run create a 16kb binary file that you can BLOAD straight into VRAM...

Almost finished my Game Boy ROM/Save Dumper for the N64 Transfer Pak

I've been working on a small N64 homebrew project called GB Transfer Dumper, and it's almost ready.

It lets you use an original Nintendo 64 Transfer Pak to read Game Boy and Game Boy Color cartridges and dump them directly to a SummerCart64 microSD card.

Right now it can:

  • Dump GB/GBC ROMs as .gb / .gbc
  • Backup cartridge saves as .sav
  • Restore .sav files back to the cartridge
  • Display cartridge info such as mapper, ROM/RAM size, battery, RTC and rumble support
  • Show transfer progress, speed and estimated time

Everything runs directly on the N64 using libdragon + libtrpak. ROMs are streamed to the SD card, so it doesn't need to keep the entire cartridge ROM in RDRAM or require an Expansion Pak for larger dumps.

Still doing some testing and cleanup, but it's getting pretty close.

GitHub:
https://github.com/alexishida/gb-transfer-dumper

Would love to hear what you guys think, especially if anyone here has a Transfer Pak + SummerCart64 and wants to test it.

How 2004 RuneScape fit a multiplayer RPG into 56k dial-up

A decompiled 2004 RuneScape 2 client reveals an obsessive effort to waste no bytes, squeezing a 3D world of thousands of players through roughly 5 KB/s. The Java applet sandbox forced everything down one TCP connection, and the server advanced in 600ms ticks, so the battle came down to bytes, not latency. A walk sends only path corners as coordinate deltas, so a single step north costs seven bytes. Each client mirrors nearby players, and updates carry only what changed: bit-packing turns "nothing changed" into one bit and a step into seven. New arrivals get positions relative to you, ten bits instead of thirty-two. The protocol enciphers only the opcode byte and mangles others to deter cheats.

How to get started into Sega Megadrive/Genisis game development

Hi, I really want to get into makeing Sega MD games. Iv playing them for pretty much my whole life on a emulator my dad gave to me. I'm 15 and almost 16 rn. I love it so much I'm extremely aware of all its limits. But do you guys have any recommendations on what tools to use. I want to do in as close way as they were made in the time so I want to do in pure assembly. Iv done computer science + my dad has done assembly with the same processor as the Sega md before so he can teach me. And secondly what do you guys recommend I use for graphics. I mean like pure pixel art. Also for music I already use furnace and have seen its txt export wich im pretty I can convert to the games format once I learn assembly with a python script as I know python! Also excuse my spelling and sentence structure I'm a little dyslexic lol. But ty for reading any recommendations would be awesome. But pls can u say the most memory efficient options as I myselfe am obsessed with compression and makeing cool stuff in the smallest file size as possible!

Grandleon - Tactical RPG Engine and Editor

Hey folks, sharing here a project I've been working on called Grandleon. It serves as an engine to create games similar to Fire Emblem, with a web editor to create the campaign with maps, units, cut scenes, etc.
It's still at fairly early stages, but I wanted to share and see if folks had any feedback. Issues, comments, contributions, etc. are all appreciated. Right now it can build a N64 rom as well as a PS1 disc, and the idea is to keep it multiplatform and possibly extend in the future. Including improvements to graphics (README has a few screenshots/animations, you can check out).
There's a sample game on the github page in the releases section if you want to test it out as well.
