This info, in convenient zip format: http://www.mediafire.com/download/47t9406pda2s9s2/Densha_de_Go_64_train_controller.zip First, a diagram: Returned controller status values: 20 04 00 Joyport Mapping: start 10000000 select 00100000 A 40000000 B 80000000 C 00200000 Throttle returns fixed values for each state. From top to bottom: 28000000 切 (off) 21000000 1 20000000 2 09000000 3 08000000 4 01000000 5 The brake has a series of divisions from 000E0000 on the left to 00000000 on the right. Between each division (between clicks on the left and ranges on the right) the value 000F is passed. 000E0000 解除 (release) 通常ブレーキ (normal brake) is the blue range on the left. Each value is a fixed "click", though 000F0000 is returned between values. From upper left to the bottom: 000D0000 000C0000 000B0000 000A0000 00090000 00080000 00070000 00060000 非常 (emergency) is the red zone on the right. It does not have fixed "clicks"; it is divided into five equal divisions, returning 000F0000 between the values. Pretty sure the game slams on the brakes full regardless the exact value. From left to right: 00050000 00040000 00030000 00020000 00010000 00000000 At this point there is a "click", then a final step all the way at the right. This also returns 00000000 when set, serving only as a lock for the brake when at the station so the brakes aren't accidentally released. -Zoinkity
