I am honored to see people reusing my sprites to make games. Theres a few suggestions I'm going to make now.
1)
Ok, it would seem you have a link to the wrong RTP. I was able to find the correct RTP at FTT:
http://www.foxtalestimes.com/Games/SSJ5/RTP.zip
After extracting both the RTP and the game, to make it work I had to merge the folders, that is copy all the files in the 'RTP' folder into the 'Project A' folder.
This should fix the systemC error that people have been expierencing, as systemC is a .png file in the 'RTP\system' folder.
2)
For Shop and Inkeepers, you can put the event code into the shopkeep themselves, because RPG Maker has a builtin 'talk over counter' feature. However, you need to make sure that the tile you are using for the shop counter is registered as one.
You can configure these tiles using the Database->Tileset->Upper Layer->Counter Flag
3)
Some of your map changing teliport events are trigered by walking on the tile, but some of them have to be triggered with the action button when standing on a specific tile. It will be easier on the players to have more consistant and predictable map changing.
