A decade ago (wow) I made a post about a NPDP cartridge I got that had Heroes, Riders, and Shadow builds. I was finally able to dump the cart thanks to some help and also found a 4th build on it. Enjoy and hopefully discover some cool things. https://hiddenpalace.org/Shadow_the_Hedgehog_(Trial_Version) https://hiddenpalace.org/Sonic_Heroes_(NPDP_Prototype_2) https://hiddenpalace.org/Sonic_Heroes_(NPDP_Prototype) https://hiddenpalace.org/Sonic_Riders_(NPDP_prototype)
Shadow appears to be the Tokyo Game Show build, I'm uploading an edited rom with the text changed to english from japanese. The level select screen is hard coded as japanese sadly but pause/etc should be english. I didn't change the voices to english. I'll also upload a copy that unlocks the full game incase it has changes. But this seems doubtful with the rom being after release. EDIT: https://mega.nz/file/2clUDZ6A#CPFElI5jwbkVKwH6K0p9LQ3GszlyrTskg-hKleL9G88 This rom is the same as MSX posted but I hex edited the configs to make the text english where it's possible. There was a mention about a debug menu but that crashes. Also, the roms main.dol is 5.52MB vs 5.50MB on retail.
Thanks to Sewer56 on the Hidden Palace discord, the Heroes build that didn't boot now boots. Looks like it's a full debug build. Spoiler: Big pictures
Shadow the Hedgehog Trail Version/TGS menu images: Also credit to Sewer56 for finding the working E3 menus in the game: Spoiler: E3 menus
