Commodore 64 Forum
The 8-bit that ate the 1980s.
The Commodore 64 ran from 1982 to 1994 and nothing else in its class came close to matching its sales. The community never really stopped either — there are still new games, new demos, and new hardware mods shipping in 2026, plus an archive of roughly 10,000 original titles to work through.
Inside the machine: MOS 6510 CPU at 0.985 MHz on PAL (1.023 MHz on NTSC), 64 KB of RAM with about 38 KB actually free once BASIC is loaded, a VIC-II chip doing 16 colors and 8 hardware sprites, and the SID — 6581 in early units, 8580 later — whose analog filters are the reason people still care about this chip in a way they don't care about most other sound hardware of the era.
What the community works on:
- Games — both the original catalog and a healthy pipeline of new homebrew. Recent standouts include Sam's Journey, L'Abbaye des Morts, and the ongoing RGCD cart competitions.
- Hardware — recapping (the electrolytics are all past their service life), PSU replacement, JiffyDOS, SD2IEC, 1541 Ultimate, Kung Fu Flash, Easy Flash 3.
- Programming — 6502 assembly is still the standard, usually through cc65, KickAssembler, or ACME. Modern C options exist too: KickC and Oscar64 both produce usable code.
- Music — the SID tune archive (HVSC) is past 60,000 tracks. GoatTracker and SID-Wizard are the workhorse composition tools.
- Preservation — tape imaging, disk copying, and ROM dumping are still happening; cartridges keep surfacing that nobody knew existed.
Buying one: On eBay, a tested breadbin or C64C runs $80–250 for something that actually works. Budget another $40 for a modern replacement PSU before you plug the original back in — the 1980s bricks fail in ways that kill the motherboard.
Getting started cheap: VICE runs on anything, reads every common disk format, and is the reference-accurate emulator the cracking scene itself uses. Our C64 file exchange has the software; the forum is where the hardware questions go.
Frequently Asked Questions
What C64 emulator should I use in 2026?
Updated answer with more detail.
Where can I buy a working Commodore 64?
eBay is the usual source. Expect $80–250 for a tested breadbin or C64C in 2026. Dedicated retro shops (Retro Ready, TFW8b, Retro Innovations) charge more but ship already-recapped units. Also check the marketplace forum here.
Why does the C64 PSU matter so much?
Because original "bricks" have a 40-year-old linear regulator that can fail in a way that feeds 12V into the 5V rail. When it goes, it takes the RAM, ROMs, and sometimes the CPU with it. Always replace the original PSU before plugging it in — a modern switch-mode replacement is roughly $40 and pays for itself the first time you plug in your C64.
What programming languages run on the C64?
6502 assembly is still the standard — usually through cc65, KickAssembler, or ACME. For higher-level options, KickC and Oscar64 are modern C compilers that produce usable code. Pascal and Forth implementations exist but are niche. BASIC V2 ships in ROM and is fine for learning.
Breadbin vs C64C — does it matter?
Only cosmetically. The "breadbin" (1982–1986) and the slimmer C64C (1986 onward) are electrically compatible. Late C64Cs have the 8580 SID, which sounds different from the earlier 6581 — neither is better, just different. Most software sounds right on either, but some older games were tuned for the 6581's filter.
