One of those games in that list is definitively in my willing to do list 👀

There is a certain balance in an outlined sprite, that makes it look considerably smaller when you remove the white part. This is why the bat has actually bigger ears and bigger wings (1px) in the #gameboycolor version of #tinytoon DX 2. Not using it as a cheap reason to show you my progress at all

A side to side comparison of the "western mine" level in Tiny Toon Adventures DX : Montana's Movie Madness.
A closer look to the bat makes you realize I have added one pixel to the wings and ears, so that the general size of the sprite remains the same.

Some hours ago I finally built a Donkey Kong DX ROM that has EVERYTHING colorized. The game can be played from start to finish without a single B&W pixel.

Revealing one of the things that's next for Project Satellaview. I wonder if you can tell the difference...

Been waiting for this to happen for decades 😍 Thank you for the work and good luck, can't wait to play the definitive version of BS Excitebike at last.

A must read on how AI is specifically making a significative decrease of quality in ROM hacking and homebrew.

While betatesting Mole Mania DX @retroachievements.org found an non colorized room :-(
Time for an update I guess! I will be doing a full 100% walkthrough just in case there are more unfinished rooms before that.

I thought the mouse enemy looked a little bit dull and monochromatic in my #tinytoon colorization patch for #gameboycolor. So I took inspiration from the coyote gang episode, and changed the color of his hat ever. 😊 BTW, I'll be taking part to a retro event soon, and a demo will be playable.

A comparison of "Tiny Toon Adventures : Montana's Movie Madness" on Game Boy Color. The enemy's hat used to be white, but now it's black, reminiscing the "coyote gang" episode of the series.

Here's the first footage of the cancelled SNES/SFC port of Railroad Tycoon to ever be posted online, captured from my promotional tape made by the would-be Japanese publisher. For a long time, the only evidence of the game's existence was two blurry Nintendo Power screenshots!

Someone claimed to have uploaded the SNES prototype of Project Dream that they had in their personal collection on Archive.org. This is footage by OlieGamerTV. We don't know if its authentic but it works.
