Level Data
Level data is located in 2 separate pages in ROM memory. Each level has a starting address, where a list of events are read. Some events jump to other addresses, and can even jump to a "subroutine" of events that will be executed, and then the level will return to the event immediately after the calling event. The level data can be viewed as a language or instruction set to be read one instruction at a time and interpreted like any other language. Some events include native CPU instructions that will be executed before the next event is processed.
Level Events
Each event starts with an event type byte. Each event type has a different structure length.
