I've polished this up quite a bit, there is some information here: http://mynesdev.blogspot.ca/2012/09/ca65-highlevel-macros.html The expression evaluation code has gone from a huge pile of .IFs down to this: .macro process_expression_FLAGS flagtest, flag, flagisset ; Find a value for which flag we ...

I added greater and not greater. I also made some the flag checks more restrictive, like a flag name (Z for example) has to be followed by 'set' or 'clear'. I may add a do while loop and get back to actually coding some 6502. If anyone uses this and needs the code to be relocatable, change the jmp i...

I would think it might be worth exploring what you don't like about ca65 and see if you can work past those things or learn to appreciate them.

So I was implementing ELSE and I realized that trying to track IF/ENDIF pairs with numbers and math doesn't work. It may work most of the time, but it doesn't work all the time. The only proper way to do it is a stack, and actually it's much easier. So ELSE is working and IF / ENDIF should be 100% r...

Would it be hard to make macros for greater, not greater, less_equal, not less_equal, that use a branch on Z that jumps over a branch on C? Not hard at all. It also wouldn't be hard to implement do-while loops, or repeat-until. Would "else" be hard? I briefly thought about that, it might ...

I think my brain would think about that better in terms of "is the result negative or not?" rather than less or greater, but I see your point. So far I have: ; carry set ; carry clear ; no carry ; not carry ; C ; not C ; C set ; C clear ; less ; not less ; greater_equal ; not greater_equal...

IF Carry Set = BCS IF Equal = BEQ IF Less = BMI(?) The macro would actually change carry set to BCC and equal to BNE since I want to enter the block of code if the flag is set. In normal 6502 assembly Less is BCC, greater or equal is BCS (after a CMP instruction). That is how I implement it in the ...

I like NESHLA but it's too limiting, and so I moved on to ca65 for various reasons. The things I liked about NESHLA I figured I could do without or get close enough to the same functionality with macros. I decided to recreate the if functionality with macros and I think it is working well. If anyone...

That doesn't sound conclusive. I use DD-WRT and have for about a looong time without issue.

There is a trick to recover it using TFTP if you haven't tried that.

I think some posts here are confusing. There are two kinds of instructions that can result in page crossing: When indexing an absolute or indirect address to find a final address - which does not use the PC, and when branching, which does use the PC and uses signed values.

Okay thanks for letting me know. I know the video on this laptop isn't fantastic - I didn't know it was that bad.

I have Intel GM965. I could look into it more, but it seems OpenGL with any filter is basically unplayable, while with filters in software mode the emu runs fine.

"Sins of a Solar Empire" is pretty good.

Is it just my old laptop's OpenGL support, or is software video significantly faster in general?
