8-Bit Show And Tell | LOAD"*",9 : Beyond Device 8 on Commodore 64 @8_Bit | Uploaded December 2023 | Updated October 2024, 8 hours ago.
Lots of Commodore 64 software is hardcoded to only load from device 8, typically a 1541 disk drive, despite Commodore making it very easy for developers to support other device numbers. Join me as we take an exploratory survey of many productivity and game software packages to assess their compatibility with drive #9, and see if we can make more of them work with a bit of hacking. We also look at how easy it is to support other drive numbers, and finally try to solve a related mystery about using PEEK(186) as a parameter in a LOAD command on C64. It's fun!
