Re: Mickey's Safari in Letterland shaking

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.

Re: 3DNes

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.

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

PPU IRQs, much like the scorebar in SMB3.

Re: A12 Timing Question

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.

Re: Defining a cross-emulator save state format

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.

Re: Defining a cross-emulator save state format

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

Re: For help,Mapper 538's mapper info!

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

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

Re: Annoyance with Allegro + key polling

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...

Annoyance with Allegro + key polling

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...
