I'm not sure if there even is an official guideline for that. Wikipedia says The NTSC and PAL analog television standards do not specify official overscan amounts, and producers of television programming use their own guidelines. while the emulator Exodus shows about 4 pixels of the left bottom and ...

I'm not sure if I understand your question correctly, but maybe this thread answers your question?
IIRC the action safe area is slightly smaller than the actually rendered image, so if the TV you are using is only showing the action safe image, it will crop the borders completely but this depends on ...

I am talking about the game some guys from DICE showed at a few years ago (https://www.youtube.com/watch?v=wD_oFVeYZYo).
Does someone know what happened to it?
Did sony deny the license, or did the guys from DICE just forget about it?

Wow, this indeed looks great. I wonder how much performance penalty it would take to make this work without the word reads from SRAM?

(Should someone wonder why I keep posting here: I will keep this thread updated as long as I work on this, so that if I ever stop working on it, the information I have gathered is still available for other people)

I have written a small test rom (as a replacement for the usual mdos.bin) which ...

I've mailed krikzz and he gave me quite a bunch of very usable information. By the time he answered I already had tried disassembling the code a bit, but I had only found out that writes to 0x80000 seemed to select some register and writes/reads from 0x80002 were used for data. But finding out which ...

Thats actually a very cute thing to do. Even if its an extremely basic game it still has some nice details to it, like proper collision detection for the roof of the house, or the fact that the toys jump to follow you if you go up a cliff.
Nice job

Oh well, I am stupid.

The graphic shows the values from F to 0 (left to right), so the strange effect in the left of the third test series is not clipping, as these are in fact the less loud clicks, while the right ones are the loud ones (and they are just the same amplitude as in the first test ...

Well, I noticed some distortion and tested it and there seems to be clipping (at least on my model 1 mega drive).
I tested the following:
All channels are always on frequency 0.
First test series:
- Channels 0 and 1 envelope set to 4 (this is about 50% of the outputrange for frequency=0).
- while i ...

I'm writing 2 samples at once. I mix one sample (-> 16 bits), then use "swap" to shift the word to the upper half of its register, then mix another sample, and then write both at once to z80. I only hog the z80 bus for this short time frame so the z80 code does not get halted for too long which ...

Thanks, thats very interesting. I didn't think of looking for information on the old everdrive. I will see how much of this applies to the everdrive v3!

I've recently been thinking about the possibilities of a custom everdrive menu (MDOS.bin), and therefore started reverse engineering how the software works. I haven't achieved much, but I wanted to create a thread to see if someone already did the same thing, has any information about it, or is ...

That perfectly fits my guess though:
As soon as you once have used it, the label "enemy" no more refers to the type, but instead refers to the object.
So
void getEnemyDistance(enemy *enemy, enemy *enemy2)
looks the same to the compiler as
void getEnemyDistance(enemy *foo, foo *enemy2)
and since ...

This is just a guess:
Is enemy a struct? If so I think it's possible to use it both as a type and as a variable name. Still, if its once used as a variable name, the variable name "shadows" (not sure thats the correct term) the type name in that scope. So if that's correct your function gets parsed ...

If the problem you are having with Fusion is the fullscreen performance, this page mentions two workarounds: http://www.blitzbasic.com/Community/pos ... st=1202630 (With this it Fusion works fine for me under win 8.1)
