Side by Side 2

To do: There's seems to be a debug test mode that has additional functionality, namely region changing and "ADTEST" (whatever that is). Toggling Dev Debug dipswitch does not enable it - rather it makes access to test menu harder. The Honda cars are disabled in the US version of the game (MAME set sidebs2u). On the other hand, in the English version where Honda cars are available (MAME set sidebs2), the SiR trim badging (and FC RX-7's "Savanna" name) is removed. Is the CPU-only Impreza Sports Wagon supposed to be playable? Was the Efini logo or name ever used in the FD RX-7 during the attract mode specifications screen? What does the Evoluzione RR revision add? Japanese Wikipedia says automatic transmission rev limit/shift points were changed and reverse tracks were added. Also, is the post-race replay RR only?

Side by Side 2 is where the series' Initial D influence begin to show up, effectively being the officially unofficial game for the racing manga, a fact reflected on one of the high score lists.

Unused Audio#

To do: Is song ID 50H used in this game? It is listed as "Ataract" in the compilation album collecting this game's songs with that from Densha de GO!, but the game uses 51H instead, which is not in the album.

Sound ID 03H is the "Side by Side" title call by itself. This would later be used in Side by Side Special.

Sound ID 0FH is the "Welcome to Side by Side" title call used in the previous game.

Free Camera#

Present in the game is a free camera mode which can be enabled in MAME by toggling the Dev Debug dipswitch on. While in-game, the steering wheel turns the camera left and right and the gas and brake pedals move the camera forwards and backwards respectively.

Car Listings#

Starting from 0x142A38 in the main CPU, there are strings referencing cars that may not be necessarily present in the game. The list mirrors the list present in Side by Side Special, effectively a port of this game that adds cars and tracks from the first game, with few exceptions.

Additionally, at 0x13E48C there are spec sheets for three DTM race cars from the 1995 season, as well as for the Mitsubishi Lancer Evolution III (which would appear in the first Battle Gear game), Honda Civic SiR (EG), Nissan Skyline GT-R (R32), and Subaru Impreza WRX STi Type RA. These are different in style compared to spec sheets used by the attract mode.

Non-string data sandwiching each entry were removed for readability.
