Back.

Just a quick note, "261-264: Sprite pattern fetch (1 of 8). A12 is high". Well, A12 is high IF the sprite tile bank set (second sprite byte) is $1000.

I have a question peeking my curiousity, have you though about trying to "predict" the future to allow for smoother scrolling? What do you mean by "smoother scrolling"? I believe he means the edges of the screen. In a few games, some backgrounds will look like a triangle. In order to fix that, ther...

That... or a bot. If human, yes, english isn't his mother-language, as far as I can tell ya.

Hi.

I registered at Famitracker forums as "ZepperFang77", and I'd like to have my account activated.

The expected result is a phone call style, right? Tune-silence-tune-silence... correct?

How did you fix the "watch dog $4017" problem in Battletoads & Double Dragon?

PPU IRQs, much like the scorebar in SMB3.

Trace logs. Among the instructions, put a warning in the log when the IRQ is requested, then another when the IRQ is ready to trigger (meaning ready for its code execution). Analyse cycle and scanline, and see why it's happening there.

About the savestate, is there a problem of setting APU (and possibly) PPU timings to zero instead of saving cycle counters? Good about saving on scanline -1. I believe it's no so hard to create a standard savestate format with tagged blocks.

The basic NES memory can't be different, along the CPU state. The problem is all about mappers, I suppose.

It's always missing some information. It looks like a hack of the FDS to be working as iNES format.

This is the game ("Exciting Soccer" by Konami, 1988).

Ok, thanks.

One word: awesome.

In what scope does char my_key=0; execute? Global or within a function? This will help me figure out whether it's a static or automatic variable. It's static and set to zero on emulator launch only. Are you calling poll_keyboard() ? What does keyboard_needs_poll() return? Not calling it. keyboard_n...

Hi. I'm having an annoyance in my code. Such problem wasn't present in the previous version of my program. Basically... Allegro has a volatile char key[MAX_KEYS] array that holds the state of each keyboard key, as 0 (released) or -1 (pressed). More info here . In order to avoid a deadlock on checkin...
