As promised I'm releasing 2 new Wii exploits: Another Pwn & The Haxx Bearers They both come with source code, prebuilt exploits and full, technical writeups! All links are available in the comments, enjoy! github.com/ioncodes/wii...

layle.mePwning the Wii: The Haxx BearersThe Crystal Bearers gave me my online name. I gave it a forged save table count and a surprise visit from HackMii!

Introducing: The Haxx Bearers A Wii exploit targeting my favorite game! The game that launched me into a multi year emulation development journey... The same game I got my name "Layle" from: Final Fantasy Crystal Chronicles: The Crystal Bearers! www.youtube.com/shorts/kSUQc...

Introducing: Another Pwn What's writing your own Wii emulator without also writing your own Wii exploit? Another Pwn is a savegame exploit for Another Code R, powered by a good old strcpy bug :) Dropping another one soon, incl. both writeups! www.youtube.com/shorts/iRAxw...

There are already Wii exploits of course, but it's nonetheless super cool to call one (or more) your own and be able to hack your console with *your* exploit. Especially if the Wii was your childhood favorite!

Also shoutout to my cats and my vigorous clicking

Back when I started my Wii emulator I semi-secretly set 3 other goals: 1. An arbitrary savegame based exploit 2. An exploit in my favorite game specifically 3. A system menu/IOS/Opera/whatever exploit This one is about goal 1, and let's say goal 2 is already "in the works" ;)

layle.meGBA Graphics, Part 1: Bitmaps, Tiles and PalettesHow the Game Boy Advance fills its screen from a bitmap or from tiles, maps and palette banks, explained with frames from real games.

Ever wondered how GBA graphics work? I used Sly's debugger to create a 3 part blogpost series explaining exactly how the GBA's PPU works! As always the posts are very interactive and use real games as example! layle.me/posts/gba-gr...

layle.meGBA Graphics, Part 2: Layers, Sprites and BlendingHow the Game Boy Advance picks the color of each pixel from its backgrounds and sprites, with windows, blending, fades and mosaic changing the result.

layle.me/posts/gba-gr...

layle.meGBA Graphics, Part 3: Rotation, Scaling and PerspectiveHow the Game Boy Advance rotates and scales backgrounds and sprites by working backwards from each screen pixel. It also shows how games change those numbers on every line to draw a road in perspectiv...

Sly, my new multi-system emulator, is finally public! Features multiple frontends: • A unique emulation frontend with 3D models and boxart • A stunning and very advanced debugger • A minimal, classic Qt based frontend • iOS, with Android planned Link down in the comments!

layle.meMario's Missing Eyes and Sunshine's White OceanOne fix in Gecko restored Mario's eyes in Galaxy and the ocean in Sunshine. Both bugs came from overflowing alpha values!

Another blogpost got approved! This time we're going to talk about a bug that has been haunting my TEV implementation for ages! layle.me/posts/galaxy...

layle.meWPAR: Why Metroid Prime's Geometry ExplodedWanna find out how a missing write-gather reset corrupted Metroid Prime's model coordinates in Lazuli?

I recently helped out a friend debug a bug that appeared in Metroid Prime on his GameCube emulator! During the initial cutscene, vertices were flying around on the screen crazy style and the actual root cause is extremely interesting! Enjoy! layle.me/posts/wpar/

layle.mez-freeze and Mario Golf's Disappearing MenuMario Golf's menu signs were being covered by the sky because Gecko was missing z-freeze, a GPU feature that lets one triangle borrow another triangle's depth.

19 Sept

It's blogpost time! I recently came across and reverse engineered 2 "obscure" GPU features that only a handful of games (ab)use on the GameCube and Wii! Both blogposts are full of interactive visualizations :) I introduce (2nd blogpost in the comments): layle.me/posts/z-free...

layle.mevertex-skip: The Case of Luigi's Extra TriangleA stray triangle stretched across Mario Golf's menu because Gecko drew a vertex the game had told it to skip.

19 Sept

Interested in learning why Luigi grew an extra triangle instead? layle.me/posts/vertex...

Gecko, my cross-platform GameCube and Wii emulator is finally public! Many games already work extremely well :) It's not only tailored to the average user but is also packed with tons of features for reverse engineers and developers! github.com/ioncodes/gecko

I started doing emudev on December 8th, 2023. I spent almost every day working on emulators and learning about them! The goal? Emulating the game I played for years as a child: Final Fantasy Crystal Chronicles: The Crystal Bearers on the Wii. This game gave me the name "Layle"! The day has come...

3 May

I can't believe my eyes still. My journey was: Game Gear > GameBoy > GameBoy Color > GameBoy Advance > PlayStation 1 > GameCube > and finally the Wii

IPL goes into menu properly!!! even looks very decent besides the fact that there is no animations at the very start

Layle@layle.bsky.social

made some crazy progress this weekend implementing the gamecube gpu in my emulator

21 Mar

so apparently it's normal that there is no animation. there's only an animation if a game is present (which im currently not doing)

5 Nov 2025

The first 2 games are playable: Puzzle Bobble 2 and Mortal Kombat 2! 3 months deep into this emulator (now with shader support in case you haven't noticed!) and still so much more to do....

PS1 emulator & debugger progress update :-) BIOS fully executes without any (known?) issues

29 Sept 2025

My personal blog is about to get a facelift! I used to use a slightly modified Hugo theme, but it never really felt appropriate for me... So I ended up making my own during a 24h session using Astro! You can see the old blog for comparison towards the end of the video.

24 Aug 2025

ended up making a trace explorer for my PSX emulator. it's technically compatible with any output generated by the "tracing" crate (Rust) as long as JSON output is enabled

28 July 2025

my GBA debugger received a major face lift, it looks so much better now. it's also less chaotic than it used to be due to me ditching floating windows for everything

old screenshot for comparison

youtube.comayyboy advance (ayydbg) - Golden Sun [Update 1]YouTube video by Layle (ion)

Implemented some SFX features, the color effects look fantastic now :D They are extremely noticeable in Golden Sun (notice the colors near the windows or the candle in the next scene)! www.youtube.com/watch?v=1T7U...

youtube.comayyboy advance (ayydbg) - Legend of Zelda The Minish Cap [Update 2]YouTube video by Layle (ion)

The effects are also quite noticeable in Minish Cap www.youtube.com/watch?v=1WPW...

window support was actually also required for Minish Cap to display the text in the intro scene properly. the window is used to daren/lighten up the text to create the fade-in effect

I published the website that hosts all screenshots taken from my emulator! It's super useful to track my progress and figure out what feature caused which changes across an entire ROM collection ayyadvance.layle.dev

26 June 2025

Massive progress on my GBA emulator, most titles now at the very least get into menu if not ingame with many being playable!! Still lot's of features to add and bugs to fix... Been working on the project for almost a year now (with a few breaks inbetween)!

Some of my childhood favorites like Wario Land 4 and HP Chamber of Secrets work dangerously well! I recorded short videos yesterday, here's Wario Land 4: www.youtube.com/watch?v=y3zz...

30 May 2025

also added a sprite viewer. the sprite viewer and the built in script engine (not on video) helped greatly with figuring out a small bug that had a huge impact on the sprite<->background prio... kirby is officially the first non-bitmap mode game that is fully working :D

My GBA research emulator can finally run OpenLara properly

31 May 2025

i also made a tool that executes a rom collection and takes a few screenshots every now and then. the screenshots can then be viewed on a simple website. this allows me to keep track of progress and understand better how "lax" certain games are

and apparently Wolfenstein 3D as well (it's choppy cause I have all debug features enabled, it's much faster without them)

noviy.layle.devNoviy Disk No-CD Patcher

19 May 2025

I think this was the last update I'll make on the DRM auto-patcher - it has been tested with titles that are not on the compatibility table as well, and everyone has reported success with it c:

Layle@layle.bsky.social

The entire tool has been rewritten to Rust and is now also published as a web application over at noviy.layle.dev! The Rust<->WebAssembly glue is a bit janky, but it works! Lots to improve but the tool works with all LEGO titles I could get my hands on so far!
