Fixed vertical delay, retreated from my previous thought about adding the one extra cycle of sprite delay, at least temporarily.

I think unit testing this thing is the only way forwards. Started adding appropriate hooks.

In C++, I think the implicit cast to bool negates the need for any manual collapsing?

Shunted the collisions buffer onto a separate area of the heap for the time being, as a debugging aid. Also added a few more initial values.

All that's happened to position is that numbers have been added to it. So it can't be negative, given that it wasn't before. So a regular modulo will do.
|
2017-02-11 13:34:36 -05:00 |

Added the four-cycle playfield output latency and ensured you can't get smaller-than-usual pixels by rapid register value changing.

Made an attempt to introduce an intermediate buffer that ends up with a bit mask of all graphical components present on it, and to use that to infer collision flags and colours, based on playfield priority and colour palette. Immediately yielding: a blank screen. Good work!

Attempted to reintroduce enough logic to handle [most of] line timing, such that WSYNC works. Initial objective is to get back to having a working background.

Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like.

2017-01-28 21:46:40 -05:00 |
|
Thomas Harte
|
0ffded72a6

Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

0182b0483a
|
Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that.

|
Thomas Harte
|
31b26b8118
|
Made a first attempt to implement the full top-to-bottom change of clock rates, giving the Atari the ability to change rate when it switches to PAL mode, as it should always have been.
|
2016-06-20 21:47:27 -04:00 |
|
Thomas Harte
|
88e2b382e5
|
Made an attempt at a full and thorough 6532 implementation (and got a bit more explicit about flag size in the 6502).

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong.
|
2016-06-02 19:50:16 -04:00 |
|
Thomas Harte

|
Made a very basic stab at a couple of the tone generators, added straight-through path for the speaker when input rate exactly equals output rate.

2016-06-01 19:53:16 -04:00 |
|
Thomas Harte
|
40c4544fb7

Got the basic sound pipeline pumping, just enough for static-level audio seemingly to work. Berzerk VE says "intruder alert, intruder alert", anyway.

Thomas Harte
|
5c4f35e13f
|
Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.

Actually, the four-clock delay, with palette taking effect immediately, appears to be correct. So back to the drawing board on that.

Threw in missiles. To 'complete' graphics output. Or, rather, to move me on to debugging.

Attempted to generalise on pixel counter storage, at least. Further adjusted background timing but I'm still not sure.

Added something of the ball counter, but without yet a working HMOVE it's prone to error.

Generalised slightly, to allow events to be queued up to eight cycles in advance; most importantly each event gets to pick its own delay.

Introduced a four-cycle delay between playfield fetch and display, curing Yar's Revenge. Also disabled barrel roll scanling colouring again. I really need to make my mind up on that.

These functions appear correctly to model the NTSC and PAL palettes; the CRT's attempt to switch function doesn't work properly yet though.

Oh, of course, it's that the output vertex array doesn't get initialised unless there's an RGB shader program. Silly oversight. Fixed. And switched back to TV output for correct colours.

Added a dump-the-input default RGB output shader. Which at least proves that the Atari 2600 is generally still working.

With the provision of an extra hint to the CRT and, finally, the realisation about why my scans weren't exactly joining up, improved output precision.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Got a bit higher level in CRT timing specification. Which internally allows it now to infer the colour clock frequency. Which will be helpful momentarily.

Set about documenting the CRT; while doing so decided to add an optional clock divider for input; having done so decided to try to exploit it with the Electron.
