I've been thinking of getting once since October, but still having second thoughts -
First, does the board come with the sound package you ordered it for? Because trying to make your own from *standard* ROMs seems oddly incomplete. Some examples -
1. How do you create waves that only part loop? (Example - original ROM musics with 'intros'. Like WCS's drumbeat leading into main music.) You can't loop PART of a wave file/MP3.
2. Stripping them from M3 / 'Bridge' seems very poor, since it won't move past a music that loops unless you manually tell it to - this would require then having an audio software package on your system to edit the sound file down to a perfect loop.
3. The 'lists' file that they give you to download is missing a LOT of games. (Apparently, of all the games I've looked at, only WCS was in there. No JY or RS..)
4. Folder names - there's some horribly misspelled folders in the 'folder zip' files available for games. Most recently I was looking at JY, and saw 'player_on_is_a_soft_nudge'. Seriously, what's a soft nudge? It's "Player one is top notch". For all four players this is there like that. (And that's just one example of many).
Edit to add: No mention on any of the speaker upgrades whether the amp is expecting 4ohm or 8ohm speakers.
So not being able to easily change between games for STOCK sounds - based on what has to be done above - has put me off on getting one for now.
