The first legally released English PC RPG Maker. Unlike other RPG Makers, you can use it for scripting, and it no longer has a 256 color limit.
Whereas RPG Maker 200X had no scripting system and a character graphic size limit, RPG Maker XP features an easy-to-learn RGSS (A form of Ruby with closed-source components) script editor, no character graphic limit (although the maximum size of each graphic is 640X480 due to the resolution of the engine), and allows the use of most common file types.
It was released in English mid-2005 and the 30-day trial is available for download at various websites, the most known being download.com, where the purchase is also available. The program costs $60.
Before the program was legally translated, a few members of various RPG Maker communities made translations and/or patches. The most famous of these are DynaEmu, who made the first hack of RPG Maker XP, RPG Advocate, who made the most widely-used version, and Dubealex, who created a patch of RPG Advocate's Translation that allowed 4-line messages and a bigger event-script box.
Throughout the years, when the legal XP was released, hackers began making key generators, which simulated the purchase of the program. Most of these hackers, however, were too rash in their actions to distribute their key generators, and most of them have already been banned from most RPG Maker Websites for distributing them. Upon the legal English release, many sites (most notorious being rmxp.org) banned distribution of information leading to illegal (hacked) copies of RPG Maker XP in an attempt to show their support of Enterbrain's decision.
