    Doesn't matter if it works or not, giving up the audio sounds like a horibble tradeoff.

    If you are that desperate to play the game without sound then just buy it or use that money for a better Mem stick... That's a worthless patch...

    The cause of the troubles does seem to be data not being read fast enough from the card.
    I dropped some of the audio from the Japanese rom in an attempt to fit it on my old EZ2 and found out that it did not crash on my EZ4. You can do the same by pulling apart the rom with NDSTool and deleting a portion of the end of the soundfile (called sound_data.sdat) and then rebuilding, I have a list of offsets for the files you can use on my site:
    http://www.4shared.com/file/7846194/59a6fbf/PORsound.html

    Later I repointed the soundfile to dodge the massive wave files at the end of the soundfile (most of the other sounds were smaller than my cards cluster size) which made it far more stable again but did not sacrifice too much sound.

    Interesting stuff. I didn't know you could disassemble roms like that. BTW, if you want to look at the C:POR file list + offsets, open the XML he linked to in Excel. It'll give you a nice row/col format.


    Here's a sample:

    .........................offset...size.....size(dec)

    The supercard has patching tools to either speed up access to the game or make it run faster. I wonder if they could do something like that to get castevania to work. Getting rid of some of the sound files is just too much sacrifice to play it on the R4.

    I can remember on the supercard you used to have to patch the rom to supercard instead of SD. You could only do this with 32MB roms, the roms that froze it managed to fix. Supercard seem to have sorted out the problem now, I just hope the R4 team do the same.

    I wonder if editing Tony Hawk DJ could speed up gameplay. It runs at 80% speed on all microsd carts. Perhaps remove music or rearrange files... More on the slowdown here.
