I haven't seen a video yet which compares the timings of the different Game Boy players available for different consoles so I felt like fixing that. In my video I have compared the original Super Game Boy (SGB1, top left recording), Super Game Boy 2 (SGB2, top right recording) and Game Cube Game Boy Player (GBP, lower recording). All 3 devices have been recorded with the GV-USB2 capture card at 59.94 frames per second. I have used Amarec 3.10 as capture software and the raw files have been encoded with Yua. All recordings start and end at the same frame of the game to ensure accuracy. As game I have picked Castlevania Legends as it features an in-game timer which doesn’t just go for 5 minutes but a bit longer. I have disabled the audio of the Super Game Boy 1 because it is running way faster than the other 2 devices and that would cause one big mess with the audio (audio is already a bit off because of different speeds of SGB2 and GBP). Not to mention the disturbing high pitch of the SGB1.

The Super Game Boy 1 and 2 have been attached to my Super Famicom and the Game Boy Player has been used with my Game Cube.

Lengths of the recordings in the video:

Super Game Boy 1: 40434 frames (@59.94 = 11:14.34), Super Game Boy 2: 41413 frames (@59.94 = 11:30.54), Game Boy Player : 41379 frames (@59.94 = 11:30.20)

It was already known for years that the Super Game Boy 1 is running faster than original Game Boy’s frame rate so no surprise here. SGB1 is running 979 frames (00:16.20) faster than the Super Game Boy 2. What surprised me a little bit though is that the Game Boy Player is also not as accurate as the SGB2 (GBP is running 34 frames faster or 00:00.34 than SGB2). It’s not as dramatic as the SGB1 but still worth mentioning.

Also I wanted to say that I have tested different games as well (Super Mario Land 2 for example) with similar results (SGB1 running like crazy, GBP several frames faster than SGB2) so it’s not an issue of a single game and seems to be hardware related (or maybe software related/ GB Player disc?). This needs additional testings from someone who is more knowledgeable than me.

What I haven’t tested yet is the GBI (Game Boy Interface, http://www.gc-forever.com/forums/viewtopic.php?f=37&t=2782) for the Game Boy Player which is said to fix the „speed issue“ of the GBP. Would be nice if someone with GBI and SGB2 could test and compare them.
