Thanks.
Thats cleaner than how I was doing it.
I had been writing functions to return addresses, etc..

CC65 syntax related question (not CA65)
I've coded for years in CA65 and after seeing some amazing work done using CC65, I've decided to try my hand at it. However I have encountered some problems in trying to convert CA65 ASM syntax into something CC65 likes. For now, my workaround has been to make ASM libraries and just call those any t...

I'd just like to thank you guys for the responses to this post. Based on some of the answers, I was able to fix my emulator to finally show SMB title screen. I had already known about the 1 byte read delay, but for reasons I cannot fathom, I was taking the address and masking it to be 0x2000-0x3FFF ...

One problem that hit me and tool me a while to fix was related to doing a Sprite DMA late in vblank. It was invoked during VBlank, but AFAIK the entire operation did not complete during VBlank. On real hardware (and Nintendulator) my sprites did not show up. On FCEU, which was my default emulator, t...

I tried running lots of different test roms. I found that I might pass a test, then implement something new (like IRQ) and end up breaking those earlier ROMs. Then I'd add APU (and its IRQ) and re-break things again. Galaxian and Super Mario Bros (title screen) are 2 games I could never diagnose. Ma...

I use ca65. I run cygwin and have a certain familiarity with Makefiles. I do not think I use all of its capabilities though. In my early coding days, I was making multiple wrongs and somehow getting a right. I usually just have separate ASM files broken up by functionality and then include them all ...
