Thanks a lot! I've just finished it, playing it just after having finished Goemon Gaiden 2. I was curious about this little classic rpg for quite some time, and I even played the prototype Taro's Quest a few years ago, thinking it would never be translated.
I've found a few things I'd like to share in case it's useful to anyone interested in giving it a try:
These are the addresses to modify some values in the game, that I've found fiddling with the last Virtuanes
jajamaru current exp 065D - 065E (change the value in these two addresses to 255 and you'll start the game with 65535 exp, the maximum reachable for the characters, and you'll rise to level 32 after the first combat)
sakura current exp 065F - 0660 (same as the previous cheat)
money 0659 - 065A (change this two addresses to 255 and you'll have 65535 gold)
enemy boss moki HP - 067E (change the value to 0 and you'll defeat the final boss in only one hit)
And here's a "no random encounter" code I found in a Japanese cheat site. You can use it in Virtuanes by creating a specific vct file for that game:
Thanks again for your work, guys, I wanted to play this game for a long time.
