A few months ago I started my project and working to support multiple platforms including: Linux, Wii, 3DS and just started to add PSP. Before I restarted to make it multi-platform I did a lot of testing on the 3DS because it is portable and easy to carry arround. My original goal was to write it for the GameCube and Wii but that looked scary when I was just getting started. To give an idea of what Batterycheck is here is the description I wrote in my PSP thread:
Back in 1998 there was a campaign to promote recycling batteries in the Netherlands and part of that was a PC game on CD-ROM you could get if you brought 15 batteries in for recycling. It was based on the same engine as Jazz Jackrabbit 2 and therefore uses the same fileformats for the Tileset, Levels and Sprites. About 10 years ago the game was released as Freeware by the publisher but they removed it after a while. After some digging I found one of the companies that worked on the game and I contacted them. The game is licensed as Creative Commons but I need to ask them which specific version. I did get permission to share their download page where the game is listed but they warned about it getting removed in the future. I posted the link and instructions to download in my other thread (here)
I found a Let's Play video in English and they play through the entire game to the end boss..so it has some spoilers ;)
An error occurred.
Just to be clear this video is NOT of my version of the game engine.
