Wow!

This is so cool! When and where can I buy one? Assembled of course. :)

DASM Frontend...

I've created a small utility (.NET 1.1 required) for the DASM, 6502 compiler. I was so tired of playing around with DOS-programs so I created this frontend for it. It's in a very early beta-stage so use with care at the moment. Anyway, it allows you to edit your asm-files and compile & run them in y...

That is so cool! However I can't seem to find an emulator that displays it properly (or is it coded to work on the hardware perhaps?)

Anyone knows exactly what error #5 means? :)

I think I've located the problem.. When the testprogram does the "critical" LDA $2002, it's only on row 189 in my emulator, so obviously the cpu-timing is somewhat off. As I mentioned before I'm not emulating additional cycles with page-crossing but it shouldn't differ this much I think(?) EDIT: My ...

I'm doing NES NTSC emulation so... My CPU core passes the nestest.nes actually so that's not the problem. If I am not mistaken, isn't bit 7 of $2002 cleared when read? Wonder if this might cause the problem.. Have to do further investigation obviously... I have myself to blame but I don't have any k...

Many many ROMs actually run fine and I'm sure I'm setting this bit, perhaps at the wrong time then. I can't run any of his tests almost cause I get something like "basic frame timing wrong" or similar and I bet it's because of the problem mentioned. When does the test expects this bit? I mean, on wh...

Doesn't seem to help, obviously I'm doing something else wrong. I'm not emulating additional clockcycles for page-crossing if that could cause trouble...
The sourcecode for the test isn't helping me much. I'm a guy, I need diagrams and drawings to understand this kind of stuff. :)

vbl_nmi_timing / frame basics test

I've started to add better timings in my emulator and I've tried blaargs ROMs (great work by the way). However I get error #2 when trying the ROM mentioned in the topic. So it means that vblank flag isn't set.
I set this at scanline 240, is it wrong?

Devcart news?

There's been alot of rumours for a few years about upcoming NES devcarts/flashcarts/similar but sadly none of them (to my knowledge) has ever been manufactured.
Anyone got any news concerning this matter?
I'd love a simple(?) devcart with just mapper0-4 emulation. :-)

A thing that might be cool to see inbedded in a new header format, would be a small game-banner, just like the NintendoDS/GameCube games has. An icon that could be a part of the boxart, the game logo/whatever. Might perhaps be cool in emulators, to present the game with it's banner instead of the fi...

nestest.nes where?

All url's I've found for downloading nestest.nes seems to be broken (even in the Wiki). Anyone perhaps knows a good URL?

I've tried searching this forum but searching for "nestest.nes" gives no results which seems a bit odd(?)

Thanks in advance

Kevtris NESRev?

Kevtris page with NESRev (and it's NES sources) seems to be down. Anyone knows a working URL?
