This is where I put things that can’t quite be categorized, such as “thoughts” or “status” posts.
Welcome to ISSOtm's warehouse!
Hi! I'm Eldred. I love programming, exploits, old game consoles, and writing up!
I spend a lot of my free time programming, so I have written a nice amount of free software. You can also peruse some of my projects below.
I've been tinkering with the old Game Boy for about 7 years now, so I have become a fairly active member of GBDev. Which, speaking of, I am also making a tutorial for programming your own Game Boy games (with some help) that is getting some praise as of late.
This ad is for a site that I think you may enjoy, not some algorithm. No strings attached, I'm not even paid! Here is some context.

Fibrs
Fibrs, to be pronounced “fibers”. A dev log of my developing a REST API in Rust over the course of a week.
TheZZAZZGlitch April Fools 2019
Is it a CTF? Is it a ROM hack? No, it’s both! It’s Fools2019!
TheZZAZZGlitch April Fools 2022
The yearly event returns, this time with a vengeance. A remake of the 2018 edition, fully online again, and it’s Generation III this time? Buckle up, baby!
Game Boy ASM tutorial
This is a tutorial aiming at teaching Game Boy programming in assembly, even to beginners.
You can check it out here, or peek at the source there.
Nintendo DS Action Replay Encoder
This online tool allows converting Nintendo DS Action Replay cheat codes as you find them on the Web, to and from a pseudo-code format! This should help you understand how a given code works, and perhaps tweak it yourself?
The code was written using a code creation user manual found on Datel’s website, though I have since then lost this document.
This is written entirely in vanilla JS, and although the parser is a little strict, it’s quite usable.
Pokémon exploits
Pokémon games are… not very well programmed. This leads to them being very broken, especially the first generation.
Here is a list of things I’ve written up on related to glitching the hell out of the first generation Pokémon games:
Quartet cracktro
Quartet is a great homebrew Game Boy game, published by Mackerel Interactive in early 2021. So why not do like the good old days and crack it?
In this post(-mortem?), I’ll explain what went into creating this cracktro. I’ll keep the most technical details out of the way until the end of this post, so it should still be a good read, even if you don’t have a technical background.
Smooth-Player
Smooth-Player is a system that allows stereo 4-bit sample playback at variable rates up to ~16 kiHz on Game Boy, Game Boy Color, and Game Boy Advance consoles.
This post will detail how the system works; if you only seek to use or get a demo of the system, please follow the link above.
