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.
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

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
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
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)!

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

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:

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)!
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
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
and apparently Wolfenstein 3D as well (it's choppy cause I have all debug features enabled, it's much faster without them)
My GBA research emulator can finally run OpenLara properly
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:
mandatory screenshot
I might make another blogpost detailing the entire process of automating it, as well as explaining how I "ported" it to the web
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!
browser version is slowly taking shape, im happy with it overall but it still needs a bit of love
Since I've never used Emscripten I'll likely take this as an opportunity to make a frontend where one can just drag the protected file in and it automagically does it's thing in the browser
Currently working on a tool that automatically disables Noviy Disk's custom DRM (in relation to my latest blog post) - it's been tested with 3 major titles so far and it seems to work great thus far!
