This video goes through EVERY game.
Here's the issues I saw. I only know about one homebrew/prototype.
1943 - Missing sound
Bionic Commando - Missing sound
Brawl Brothers - Running slower than SNES original
Corn Buster - Running faster than SNES original (I've played the prototype on emulation before)
Gun.Smoke - Missing sound
Legend - Running faster than SNES original (I *THINK*)
Mercs - Running slower than Genesis original
R-Type III - Running faster than SNES original
Rival Turf - Running faster than SNES original
Rushing Beat Shura (The Peace Keepers) - Running slower than SNES original
Super Earth Defense Force - Running slower than SNES original
Super Ghouls N Ghosts - Running faster than SNES original
Super R-Type - Running faster than SNES original
The Ignition Factor - Running faster than SNES original
Varth: Operation Thunderstorm - originally being a vertical shmup, they ROTATED THE SCREEN 90 DEGREES. INEXCUSABLE! (that might be an option you can set yourself, but I'm just going by the video, where he said the controls were properly mapped for a horziontal orientation!)
PLEASE FIX THIS SO I CAN BUY IT!!!!!
