I recently found on the internet the source for a patch to add SRAM save on NES Willow and that came with these instructions:
* Extract and copy the files and folders where you want to, e.g. C:\WillowPatch
* Place your Willow ROM as WILLOW.NES in the folder
* Add the bin folder to the environment PATH variable
* Run compile.bat from the command line.
This will compile the assembly files in the src folder and generate the following files:
The WILLOW.bin file will be copied to the build folder AS WILLOW.IPS along with the ROM, and IPS
will patch the ROM using WILLOW.IPS
The assembly entry point is Willow.asm. IPS_NES.INC sets up the macros necessary to generate a patch file.
The generated WILLOW.BIN is actually an IPS file that can be applied using your favorite patching application
to a clean iNES-headered Willow ROM'
I tried to follow these instructions but something always goes wrong, In Windows 10 I used vDOS but it did not work and in Windows 7 the following message appears'.ips file not found' appears, what could I be doing wrong?
