There are heaps of differences, some being character placements and no sound, but its hard to see more because the levels all direct to a boss they must have been working on at the time. So I ask you knowledgeable hackers out there to take a look at this beta and find out how to access the beta levels. I've uploaded the beta to my site here: Soleil Beta (Crusader of Centy)
Not the European. The Japanese. I searched at my source (www.romnation.net) and didn't found it. And romnation.net have a real big rom archive.
*cough* "Crusader of Centy (also known as Soleil in Europe and Ragnacënty in Japan)" http://en.wikipedia.org/wiki/Crusader_of_Centy Romnation has Ragnacënty; just put it into the search box and four or five results come up.
This might sound pretty basic, but pressig Z seems to change your current level you are playing. So I guess that would make level point edits unnessesary.
