Top Speed (World) - topspeed - Accelerator range only seems to extend to 50% #476

Closed adelpha closed 4 years ago

adelpha commented 4 years ago

Summary: Accelerator (and probably brake) seem to be analog inputs but only seem to have limited range.

Test Device: Raspberry Pi 3B 1.8.8 - FinalBurn Neo (v0.2.97.44 039fcad) XBox 360 controller

Windows 10 x64 1.8.9 - FinalBurn Neo (v0.2.97.44 27dd85f) XBox 360 controller

Steps: Load the ROM. Start the game. See how the controller's inputs behave. You can see the actual values if you enable Service Mode and goto Input Test.

Results: At least on the 360 controller, the triggers only have about half the range they should have. You cannot fully accelerate, which is ironic because this game is called Top Speed :D

Expected Results: Analog controls should have their full range mapped to the full range of analog inputs for the controller.

it doesn't seem this game has analog controls hooked besides steering, instead it has 3 different kind of gas, with "Fire 1 (Gas)" having the highest value, "Fire 7" being the middle one and "Fire 5" being the lowest one, the same logic applies to brake. It seems arcade cabinet had analog pedals : http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=topspeed&search_id=2&lang=en

Well, MAME's inputs have 3 analog inputs for Steering, Gas and Brake, plus a Nitro button and a Shifter (presumably a button but maybe a lever).

Checking out Service Mode in MAME I can see that pressing the triggers on the controller change the values for the Accelerator and Brake in a range from 0-7. So I guess the analog pedals just had 8 states.

Thanks for the report, this has been fixed on the main branch of fbneo: support for analog accel/brake added in the deluxe and mini cab-type.

best regards,
