You can download some interesting files here. These are some descriptions about them (by the way, they're all .rar files, so you'll need a .rar extractor to unzip the files):
Mario Paint Composer PC - A music composer for Windows modeled after the Music Composition mode of Mario Paint, a game released for the Super Nintendo Entertainment System in Japan on July 14th 1992, North America on August 14th 1992 and Europe on December 10th 1992.
Mini vMac 3.4.1 with System 7.5.5 + extras - The Windows version of Mini vMac 3.4.1 (presumably the 32-bit version) with all you need to emulate the 68k black and white version of System 7.5.5, a version of Classic Mac OS, along with a few useful programs that can be run in Mini vMac, which are included on the file MinivMacBootv2.dsk, a file that, if run by Mini vMac, will make Mini vMac work. Also, MinivMacBootv2.dsk is where the previously mentioned few useful programs are, and I modified it to take slightly less space.
Portii 1.0.0 - A 2D Portal-esque clone for Wii. I uploaded it because it was hard to find, but I found it somewhere on the internet.
Syphus - Mias Song MIDI - A .midi file of Syphus - Mia's Song.
WarioWare Twisted! (U) (Pre-patched) - A ROM of Game Boy Advance game WarioWare: Twisted! that has already been patched to emulate the gyroscope. I'll try to fix or help you fix any problems you have with the patched ROM if you have such problems.
Currently planned to be added later:
20 em 1 (Brazil) English translation v0.1 - 20 em 1 (20 in 1 in English) is a collection of 20 minigames released by Brazilian company Tectoy in 1995 for the Sega Master System. The cartridge was only sold bundled with a certain version of Tectoy's Master System III Compact, had no box of its own and was never sold outside Brazil. The games included in this collection are quite basic, ranging from driving games to platformers to shoot-'em-ups. None of the games have names, instead only being identified by numbers. The translation will only change the start sign to say START instead of LARGADA, but it'll come with various pictures of what various parts of the game might look like when they'll be translated into English (such pictures will be called mockups).
Button Press 3000 - Button Press 3000 is a game for ZX Spectrum that was made by Stuart Ashen as a type-in game in his book Terrible Old Games You've Probably Never Heard Of, but I made the code have less lines with it working the same way so it would be more to my satisfaction.
GlovePie 0.43 with various configurations of keyboard remappings for various controllers - When it becomes available for download, it'll at least have two GlovePie configurations for the Wii Remote (both GlovePie configurations will involve holding the Wii Remote sideways and be for Tower of Greed). When it's released, each GlovePie configuration will also come with where I intend them to be used.
Retroguru PlayStation Portable game set - All 6 Retroguru games released for PlayStation Portable, which are Fruit'Y, Giana's Return, Sqrxz 2, Sqrxz 3, Sqrxz 4 and Xump. However, they'll be renamed to their proper titles instead of what they were named when I downloaded them. Fruit'Y was named FRUITY, Giana's Return was named GIANAS RETURN, Sqrxz 2 was named SQRXZ2, Sqrxz 3 was named SQRXZ3, Sqrxz 4 was named SQRXZ4 and Xump was named XUMP. They might also have backgrounds, music and videos for game selection.
