There are a couple of really cool Metroid Zero Mission rom hacks called Metroid Spooky mission and Metroid Spooky Mission 2 which are high quality and fun to play on the GBA.
I also picked up the Resident Evil bundle earlier this year that I should fire up. RE4 is my jam.
I can still hear “Oops!” and “Oh no!” For the undo button clearly in my head to this day - Kid Pix was the shit in middle school lmao
