Gamecube DVD-ROM speed?

Anyone know what X or MB/s the internal DVD-ROM reads from discs at?

Ordered an FPGA development board and gonna attempt to go from alternative storage > DVD pinout...

So I'm thinking about what medium to store the data on right now; IDE ATA (Seems good, universal, annoying 35+ pins to account for and create code for), MMC/SD (Can operate on 3 wires or 6 or something using SPI, seems simple and apparently kingston ultra have 10MB/sec read speeds) or RAM somehow.

 

somewhere between 3-4MB/s, forget where I read it. 3.85 iirc

 

Ah awesome, so SD-card reading isn't out of the question!

 

as long as each read finishes within 10s your are good since that is the timeout.

 

Haha, 10 second timeout, think the game would be lagging like hell with that ;p

 

@splith: are you trying to do that DVD replacement project from the plans at that crazynation website?

 

Kinda, but they won't work as I'm building it all on an Altera Cyclone III chip!

 

The 10 second timeout is incase of read errors and it's only present on the NGC SDK DVD read functions (it's only software limited there).

From Wikipedia:

.

In my tests, almost all games are fine with 2mb/s as the amounts they request are quite small per second. Also, 2.0MB/s is on the inner part of the disc, as you go more towards the outside, it slowly gains speed as it's CAV.

 

From what I readt on several sites I can say the read speed is 4x
and my guess is.. 3.125 MB/s is 4x? (@emu-kidid)
