Note that it simply gets some files wrong, +and it also incorrectly renames cartridge images with an extension that +belongs to an already established extension (.jag is a Jaguar Server +executable--read on). To clarify, there are basically four major types of +Jaguar binary images that are NOT cartridge images: + + .abs + .jag + .rom + .bin + +The first type, the .abs file, is a DRI/Alcyon format absolute location +executable. These come in two different flavors and contain load and run +addresses in their headers. Note that some files which have an .abs extension +are really incorrectly labelled .bin files with no header information +whatsoever. + +The second type, the .jag file, is a Jaguar Server executable. These files +contain header information that tells you where to load and run the file's +executable code. Note that as of this writing (8/5/2005) that the GoodJag ROM +renaming tool by Cowering incorrectly renames Jaguar cartridge ROM dumps to +have a .jag extension (a better choice, and the one supported by Virtual +Jaguar, is .j64)--if you're trying to run a ROM image with a .jag extension on +VJ, it will misinterpret it as a Jaguar Server executable and likely fail to +run. + +The third type, the .rom file, is an Alpine Board/ROM Image file. These files +have no header, but are known to load and run at $802000 in the Jaguar memory +space. Again, these are *different* from cartridge dumps since they load at a +higher address than a Jaguar cartridge. + +The fourth type, the .bin file, is simply a Jaguar executable with no header. +Since these files contain no information about where they load and execute, +Virtual Jaguar does not support this file type. Go bug the author to release +either a file with headers or a file in Alpine ROM format. Virtual Jaguar is +not omniscient! ;) + +There is a fifth type of file that is supported by Virtual Jaguar, the .j64 +file, which is simply a 1, 2, or 4 Meg dump of a Jaguar cartridge ROM which +loads at $800000 in the Jaguar memory space. + +----------------------------------- +- What is Virtual Jaguar GCC/SDL? - +----------------------------------- + +Virtual Jaguar is software dedicated to emulating the Atari Jaguar hardware on +a standard PC.
