Unhandled R4300i OpCode at: 802800EC teq r0, a0 - HELP!!

[Clements]

The are only 3 valid extensions for N64 rom images, z64, v64 and n64:

z64 - Big Endian, non-byteswapped, generally preferred format
v64 - Byteswapped
n64 - Little Endian (least preferred format)

Non-interleaved formats are preferred over interleaved formats. The others (rom/usa/jap etc) are essentially meaningless, and are in truth one of the 3 main formats.

You can identify the byte order and convert between the three main formats en masse with Tool64. The byte order has nothing to do with whether a rom image is a bad dump or not like Smiff said.

ok, good to know, but is there any problems known with changing a rom from z64 to v64?.. coz changed all .rom and .z64 to .v64.. yet there seems to be no issues?

could any arise?

If you're just changing the filename, you're really not changing anything at all. If you're using Tool64 to byteswap, it's unnecessary, but it won't cause any problems.

i just changed the extension

its easier to view by file type if they are all the same extension

anyways, i've stolen this thread enough...
