Gbc splash screen

(Possibly) the splash screen, one of the images shared by the port programmer.

Re-Volt had a port for Game Boy Color developed during 1999/2000, but it got cancelled due to a few problems that prevented the development team from continuing.

One known team member that worked on this port was the programmer Quang Nguyen from Asobi Tech, who also was the person who provided lots of worthful information about the port to the community.

The code of the cancelled port is known to have been reused in other two GBC games, which were ATV Racing and Race Time.

Rumors of a Game Boy Color port of Re-Volt started on late 2017, when someone found a rare game poster at eBay containing a few platform logos, including GBC's.

Searches for the GBC port caused the game Race Time to be found in the same year.[citation needed] Its similarities with Re-Volt led a few Revolters to explore the internal bitmaps of the game. They were able to find the race start countdown (3, 2, 1, GO!), pickups and weapons sprites, confirming the game actually had a connection with the GBC port.

Contact with Quang Nguyen

On late January 2019, MightyCucumber found and contacted Quang Nguyen, who was the programmer of the Re-Volt GBC port. He answered in the beginning of February, sharing worthful information about the development history and a pack of screenshots of the port.

History

The project began on November 2nd 1999 with the commencement of the design document, initial graphic work and code groundwork.

The team had set milestones for the project, intending to release the beta at March 15th 2000 and the master at April 7th 2000, having only 6 months to make the game.

According to Nguyen, the team were running late on February, and the project got cancelled mid March. They faced problems such as the level sizes being too big and off the scale.

The game was planned to fit on a 1MB cartridge (64 rom banks, each having 16KB in size), which was quickly running out of space to add the rest of the game logic, and that was a huge problem for the team. The last version Nguyen compiled really broke when he tried to add the soundtrack. He still had 15 banks left.

According to Nguyen, the code of the port was also reused in ATV Racing besides Race Time.
