Gigadrive 0.023


I remember tyhe regional protecion, but funilly enuff, i dint smell my consoles,: :blink:

although i reckon the SNES would smell nicer

@ Josquius: The battery doesnt need to be replaced, everytime u play the game it recharges itself, but if u leave it too long they will die, and I'm not sure if u can replace em (similar problem with N64)

So if u have a Megadrive or other catridge based systems make sure u playe em every few years to make sure all ure games work b4 it's too late
 
F- DAVID....

Any chance you could get GODs to work. It boots and when hte game is about to start it hangs up..!

Loved the amiga classic ... BUT i could not get passeda certain level.. ithink it was two. You have to go into a room and get something,but you could not jump high enough to get it... and so had to reboot again... Something like that..!
Thanks.

P.s: EARTH WORK JIM works PERFECTLY..!
Play the Atari ST version.


Better still, play it on opensnes - works a treat with sound on at FS0 or FS1 at higher clock speeds and it sounds WAY better than the ST version.

Yeah tried a few other games. Some really unknown because I have the whole rom set. Some work some don't but I think you've got enough codes to work on :) I think the Michael Jacksons moonwalkere code will make a lot of other games work. And the codemasters. Keep up the excellent work Dave! Only a few games now still have issues with unlimited lives and timer (streets of rage) missing stat bar on fgen but is in gigadrive???(Dj boy). V-Five is an awesome shooter that doesn't work yet. Oh and sonic 3D blast has problems with the special stages. I'll leave you to it.

i'm guessing there a few ppl like me who cant run the newest fgen beta all it does is crash the moment its started ( my gp32 can only do 132mhz ) before you can choose the clock speeds or have i missed something ?

coz Jimmy White is Euro only i think, i could never get it to work in fgen, i havent tried gigadrive yet

BTW: does n e 1 no if there are n e other Pool or Snooker games on the MegaDrive
 
Oh, by the way, fDave, since you coded Cyclone68000, could you create an Amiga emulator...?
I need it this evening, thanks  :D

Back to Ontopic:
That's the spirit fDave... just sort those bugreports out and ignore the "I want! I need! It's uncomplete!"-posts :)

Thanks again for your great work :)
As far as an Amiga emulator, don't count on it. The GP32 or any other handheld is simply not strong enough to do it. The 68000 is only a small part of the Amiga chipset. You have the blitter, copper, 4 channel stereo sound, a multitasking OS, it is just too much.

I think a full speed no frameskip Atari ST w/full sound is certainly doable though. While not an Amiga, it is the next best thing.


Do you know I'm itching to find out about the extra hardware in the famed Amiga.... it's kind of like a continuation of the old Atari ST versus Amiga battles of yesterday.
"My Amiga is SOOO much harder to emulate than your crappy Atari ST"

...what can be in this beast which means even Cyclone cannot handle it?
I want to know why :)

4 channel stereo sound and a multitasking OS? Well the OS is software not hardware, so that isn't even releveant is it? And as for 4-channel stereo sound, well the MD has 10 channels, and even the speccy 128 has 4, so I don't see why that's a huge drawback. hell i'll bet the C64 is more complicated.

No the only thing I can see is this Copper or Blitter thing, and if they aren't as powerful as a flipping Pentium-4 then it's going to be a serious letdown for the Amiga-nah-sayers!
I thought this post was about gpdrive but it seems that people started discussing the amiga...

so I would like to put my 50c in regarding amiga emulation (I used to program the amiga using assembly many many years ago).

Some info about the various custom chips in the various amiga models are here:

http://amiga.emugaming.com/customchips.html

(far from all chips are in a standard amiga 500)

Basically, perfect emulation of the amiga is difficult since nearly all of the chips are used in any single game. OS stuff like multi tasking is simple since it is standard round robbin stuff with timers and Sound is simple too since it is not FM based but used samples.....

The GFX is a whole other matter:

Resolution wise only 320x200 variants need to be supported, since only the workbench use other resolutions... color modes same thing....

Nearly all games use 32/16/8 color modes with one or two playfields.

Sprites are the same 16 by user selected height pixel size for all resolutions.

Copper needs to be implemented completely, copper is basically a word memory mover synchronized to screen, so its dead simple. Blitter needs at least a fairly complete implementation, the blitter is a block mover... non vector games use simpler copying modes of blitter, so for most games that part of blitter operation would be enough.

For anyone that is interested in FAST amiga emulation, look at sources for Winfellow... it actually ran pretty good speed on a 486 and very good speed on a 300mhz pc.

GFX handling parts are in PC assembly for speed.... porting the most used gfx rendering to get a few demos/games running is not impossible...

For instance this function renders one line segment for two playfields...
void drawLineDual1x16mmx(graph_line *linedescription)

...and so on....

If there was a C version of fellow to start working with and selectively optimizing the most used things, getting it to run reasonably fast on a GP32/Zodiac/etc. would not be impossible. The current source in 100% assembly for all gfx code is not as easy to port....

Using UAE as the base for fast speed probably is impossible since they are going for cycle exact emulation, which is much more time consuming.

Fellow is good enough for nearly all games, but fast enough for slow hardware.... but a port would still be really difficult...

As I said thats my 50 cents on amiga emulation, dont have the time to work on it myself though....

Here`s a few games i`ve been trying in gigadrive 0.023 156mhz, I may have repeated some that have been posted already, but haven`t checked.

I`ve posted it as a picture, As copying and pasting the text file into the boards message box looses all the formating. :blink:
