Here are some articles from us containing low-level information about the C64 and its peripherals:
| Name | About | Published in |
|---|---|---|
| Very fast 2x2-FLI routine | This is probably the fastest method of doing FLI. Although having badlines every second line, there are still enough CPU-cycles left for other tasks. Mainly achieved by an innovative way of using timers, then ultimatively optimized for speed. | VN #43 (03/2005) |
| Reliably detecting PAL/NTSC | The built-in PAL/NTSC-detection has some flaws. Learn here about them and how to do it better. | Go64! (06/2000) |
| Disabling the NMI | This articles describes a way to mask the Non-Maskable Interrupt (NMI), despite its name. | Go64! (09/1999) |
| Parking the CMD-HD | How to re-program a button from the CMD Harddisk to enter/exit sleepmode. Techniques for modifying its firmware are presented as well as inserting SCSI-commands. | Dom #17 (11/2002) |
| RAM within the SuperCPU | A SuperCPU uses different kinds of RAM, namely SRAM and DRAM. This article covers their differences, especially focussing on the timing. It also gives recommendations which data to store where. | Go64! (02/2000) |
| Badlines with the SuperCPU | The SuperCPU-accelerator handles badlines differently than a plain C64. This article measures how and outlines how to use this effectively. | Go64! (04/2000) |
