How were Commodore 64 games developed?

As for images, again, resource constraints it wasn't exactly viable to save an image file and stick it somewhere, the filesystem itself would take a little too much space. They tended to be hardcoded graphics.

Today some game are still developed for it (selfsell: Look at my journal, I'm building a game in several steps here)
It's way easier today with all the cross assemblers and information on your fingertips.
(selfsell2: I also recommend C64Studio, a Visual Studio like IDE, that attaches to WinVICE to allow debugging)
Nice Cthulhu reference in your sig :-)
But isn't the unholy one using pure DirectX call instead of SDL?

I reckon the first few years of the C64's life games were written on the C64 itself, but then written on a more powerful machine in its later years such as the Commodore Amiga. Just a guess though...
Dos based PCs were used on a few commercial games. Retro Gamer magazine (http://www.retrogamer.net/) has had several articles dealing with commercial C64 game development.
The most common way was on the C64 though. PCs were expensive, and a lot of games were developed by "bedroom coders" as contractors.

Anyway, eventually other assemblers were made available, languages, etc. But most of your most memorable games probably used the Commodore supplied tools because they were solid and simply worked.
Of anything which I remember of my days on the C64, the only one which stands out anymore: Hex EA == NOP instruction on the 65x series chips. As many times as I've worked for EA (they pay REALLY well), that's pretty much appropriate, NOP.
If you want further details of C64 dev, let me know, I can probably even dig up some old 6502 assembly source files assuming they are readable after all these years.

This company still publishes C64 software:
