Kickstart patch for using NTSC Agnus chips on PAL systems
At the title link, 'Cathal' has published his project, with the help of which the NTSC version of the 2 MB Agnus custom chip can also be used for PAL systems. However, patching the Kickstart ROM file requires Windows. He writes about it:
"In view of the scarcity of PAL 2 MB Agnus chips and their ever-increasing prices, I have written a small program that can patch a Kickstart ROM so that you can also use an NTSC 2 MB Agnus chip and it will automatically switch to PAL when the computer is switched on.
The patching itself is done under Windows and the patcher needs a current .Net runtime, which should be installed automatically by a current Windows if not available.
The programme is published with source code on my GitHub page. In the future, there will also be a GUI and other supported Kickstart versions. Currently, it is used via the Windows commandshell."
The following Kickstart ROM versions are supported for now:
- Kickstart 1.2, Rev. 33.192, checksum: $56F2E2A6
- Kickstart 1.3, Rev. 34.5, checksum: $15267DB3
- Kickstart 3.1, Rev. 40.63, checksum: $9FDEEEF6
- Kickstart 3.1.4, Rev. 46.143, checksum: $BE662BCF
- Kickstart 3.2.0, Rev. 47.69, checksum: $35D98F3
- Kickstart 3.2.1, Rev. 47.102, checksum: $4CB8FDD9
