Contact the developer, maybe he can help grin

Try invaders12.bin and not invaders.bin.

The translated files: invaders11.bin/invaders12.bin
About the differents between the original, raw and translated files, I am sure robbbert can help.

It seems, the translated files are created by Rewire4k application.

Quote:
Rewire 4K

This program is designed to enable reading/writing of old Aamber Pegasus Eproms

4KB files read from a standard eprom reader should be opened using 'File/Open Raw (from reader)'
Then, press the 'Convert Raw -> Translated' button. The corrected file shows in the lower text box
If the Eprom contains a valid program, the security byte is displayed also
You may change the security byte ... the altered file is automatically translated back to raw form
Save the raw file using 'File/Save Raw (for burner)' to create a file suitable for burning
You can also save the file using 'File/Save Translated File' which is more suitable for transmission
... or for use in a simulator

The default pin conversions translate between standard 2532 pinouts and that used by the Pegasus
You may also change the pin numbers for systems with different pinouts.

I've just added the facility to decrypt the roms.

If the first byte = 0x20, it should run as is.

If the first byte = 0x02, MESS will unscramble it.

If the first byte is anything else, don't know yet, needs to be checked out.

afaik, the RAW ones are encrypted, the TRANSLATED ones are decrypted, the ORIGINALS are what the guy received before he did anything. There are a number of bad dumps, don't be surprised if some things freeze or do odd things.


Now, I'm not sure what cassettes you may have, basically Tank or Invaders cassette is to be loaded through the monitor (with L command), press Enter and the new program appears in the menu. The other cassettes (pegapong, snake, startrek, chargen, charsave), you must start Basic, then use the LOAD command, then RUN.
