Ed Armstrong emailed me Feb 22 about KEGS not working, and it was an easy
fix (for KEGS).
Here's what I said:
I looked into running it on KEGS. At the title screen, Paperboy is
constantly reading the DOC last-sampled-played register, and is waiting
for certain values to occur. As an optimization 25 years ago, KEGS only
updates the DOC last-sample-played register at 60 times a second (to
basically make it work for DOCVU, and things like it). And KEGS code
had a comment saying this should be fixed.
So I fixed it, and then it seems to play. I'm quite bad at the game,
but I threw lots of papers, and even got 250 points eventually, and it
didn't hang.
I get the same results on the two .2MG files, and the .PO file. KEGS
does not work with the .woz file, I'll need to look into that.
If you want to patch KEGS.1.16 and see for yourself, modify sound.c at
lines 1776-1779, and change it from:
---
case 0x3: /* data register */
/* HACK: make this call sound_play sometimes */
g_doc_saved_val = rptr->last_samp_val;
break;
---
to
---
case 0x3: /* data register */
dsamps = dcycs * g_dsamps_per_dcyc;
sound_play(dsamps);
g_doc_saved_val = rptr->last_samp_val;
break;
---
Just add the "dsamps =" and sound_play() lines, and then recompile.
You can probably make a similar patch to GSPort.
