Re: Problem with SMB Disassembly?
If you take out the .index and .mem directives above the .org directive, you should be able to get it to assemble on asm6 without any other modifications. x816 used those because it was actually a 65816 assembler, and those two directives were used to tell the assembler how big the immediate operand...

how different assemblers handle labels
Off-topic-yet-sort-of-not: I spent 2 hours of my time yesterday writing up how 21 different assemblers allow forcing of absolute addressing , and I really don't want to spend several more hours writing up how many different assemblers handle different syntaxes; the term "time vampire" com...

Re: "Incomplete expression." in ASM6 macro
The problem with the traditional .ifndef type include guard is that ASM6 is a multiple-pass assembler, and anything inside an .ifndef with a following .define inside it will get processed on the first pass, but not on the second. The ASM6 only states that .ifdef and .ifndef operate depending on whet...

Re: "Incomplete expression." in ASM6 macro
So both the driver and instrument/sequence data are assembled together in one unit?

Re: "Incomplete expression." in ASM6 macro
Are you trying to use include guards because multiple source files include the same stuff?

Re: Background plane numbering: 1 or 0 based?
I'm still trying to figure out how PPU2 is told by PPU1 to input or output on the EXT pins, since PPU1 has the MASTER pin (for master/slave modes).

Re: Sprite windowing not working
I can't see anything wrong with this part of the code. Writing to $210E should not affect $2125 at all, since they affect two different screen components. Are you writing to the registers in some other part of the code?

Re: Scrolling on the SNES?
Is it possible to check the PPU regs in no$snes? If it is, you should check to see if the scroll registers are being written properly. Since you have only posted a little bit of the NMI, I can't say for certain what's wrong with the code.

Re: NES power-on self-test (POST)
I'm not sure how useful this would be for the NES and its software currently, but it would make a neato possible computer permutation using NES hardware.

Re: SNES dev newbie questions
I've read this paragraph 4 times now, and it's bloody confusing. I can't reliably say I understand what it means, specifically the phrases "attempting a DMA from WRAM to this register" and "attempting a DMA from this register to WRAM". The only conclusion I've been able to reach...

Re: "Balloon Fight" and "Mario Bros."
Yes, you are. Mario Bros.'s game mechanics are different from Balloon Fight or Joust.

Re: SNES PowerPak
From what I understand, FAT cluster chains are not that hard. When a FAT-using system loads a file, it does the following: 1. Get first cluster number from directory entry. 2. Read cluster. 3. End of file? Yes, stop. No, continue. 4. Read entry of FAT that corresponds to current cluster number (i.e....
Re: spca65
I was seeking clarification specifically on the bugs that blargg found, as I've noticed blargg goes a bit more technical than the average nesdevver (sp?).
Re: spca65
I'm gonna guess that you're not happy with WLA, blargg. What kinds of bugs does it have?
