Translation (Chinese) by Sinke - v0.99.2
This translation was like most Chinese translations provided with no info, simply as a ROM. There are many problems with the hacking that are apparent in BSNES and not in SNES9x or ZSNES. There is a screenshot above which details the information about the translation my guess about it is below:
Sinke onizuka V.BR.
weareg91, mash, CYRONE
The title literally translates to DQ3 Power Plus.
