    People are stating there's a hash to disk image mismatch. So I updated the patch to match the most common dump online.

ROM must be divisible by 8Mb

Reviewed By: Ziggy587 on 02 Mar 2012

This little utility is great! For those that don’t know, it will allow you to prepare a SNES ROM for use with a 27C801 EPROM. You can remove the header, swapbin and splice all in one step! It prepares the files so that the 27C801 has a closer pinout to the SNES mask ROM (only 2 pins will differ compared to the normal 5).

In order to use the swapbin function, the ROM size must be divisible by 8Mbits! Note: 8Mbits = 1 MByte. If the ROM size is not divisible by 8Mbits, you must expand it to the next size that is divisible by 8 (8, 16, 24, 32). So if you have a 4Mbit (512KB) ROM, you need to expand it to 8Mbits (1MB). If you have a 12Mbit ROM (1.5MB) you need to expand it to 16Mbits (2MB). So on and so forth.
