Title: Galaxian≥ [Dragoon] Emulation part #1 : the boards
Post by: DarthNuno on November 26, 2008, 06:17:08 PM
This topic is dedicated to the original Galaxian≥ mission : Project Dragoon

(the other topic dedicated to the Attack Of The Zolgear mission is right here (http://www.dragonslairfans.com/smfor/index.php?topic=457.0))

Regarding the boards, no more suspense  ;)  :arrow:

(http://www.dragonslairfans.com/news/pddumped.jpg)

Holy Christ ! This is it !!! P-Man did it faster than light. He dumped the romset & documented the boards.
An important step has been done, but calm down... there is a long way to go before a Galaxian≥  emulator...
Anyway, at least the Project Dragoon roms are now safe... forever ;-) Many thanks P-Man !!!


ok, i finally documented the boards and dumped the romset..

you can download it here:
http://www.andysarcade.net/pix/G3PD.RAR (http://www.andysarcade.net/pix/G3PD.RAR)

My pcbs are probably going to be put into storage now for a rainy day, i have way too much on to do anything with them right now, still, the documenting and dumping is done...

enjoy.


In addition of the pictures/documentation included in the Project Dragoon romset provided by P-Man, I'll add additional picture & information regarding that specific romset  8)

Someone from the MAME team pointed out that i missed including OBJ3.BIN in my archive, and that VOI0 and VOI2 appear to have the same checksum.. i have added the missing rom, and verified that indeed, on my pcb, VOI0 and VOI2 carry identical data..

The archive has now been updated and i am told there is a skeleton MAME driver in place, waiting for the system 23 expert to look at it..

You guys rock!

I'm guessing it's going to take a VERY powerful PC with two monitors to run it?

Since I've never played the game (or seen it for that mater), I'm very happy to think that I might be able to one day.

In the latest Mame .128u5 Release (source update from the 7 December), you can read in the whatsnew.txt (available right here (http://mamedev.org/updates/whatsnew_0128u5.txt))

New games marked as GAME_NOT_WORKING

It's just a skeleton of a driver, but hey... seeing the name Galaxian3 inside a mame release is an historical moment isn't it ?  :-* :-* :-*

....and back on this  ;)

I got today all the boards used for the dump of  'Project Dragoon' (thanks Andy  :-*)  :arrow:

(http://www.arcadelifestyle.net/G3/various/galaxian3_dragoon_boards_1.jpg)

Very well packed, and the boards (11!) ...look like new  8)  :arrow:

(http://www.arcadelifestyle.net/G3/various/galaxian3_dragoon_boards_2.jpg)

Ok, now the next step - as as suggested by Naibo on that post (http://www.dragonslairfans.com/smfor/index.php?topic=758.0)- is to provide *ultra high* resolution pictures of all the boards, both side. I'll use these boards for that job. I don't have the right camera for that at home, but I'll do some test with a friend's Nikon D90 in these comings days.

wouldn't it be an option to simply put them on an a3 scanner?

Well, I have an A3 scanner, but unfortunately, I'm only able to use it for scanning sheets ...and nothing else  :-\  Because if what I'm trying to scan is not EXACTLY against the scanner glass, it's all blur, like out of focus  :'( I don't have the problem with my AGFA A4 scanner, but it would be a little bit complicate to assemble A4 parts... but I'll give a try once again  :ghost:

Post by: DarthNuno on October 24, 2009, 04:23:31 PM
Ok, let's try with my AGFA A4 scanner :

(http://www.arcadelifestyle.net/G3/dragoon/Galaxian3_Personal_PCB_scan.jpg)

Settings are : no compression, 600 DPI resolution!

As you can see, the board is bigger than the scanner, so it'll need multiple pass. Thanks to Photoshop CS, there is an automatic function to join multiple pictures into one  :P :-*
But note that some items may be missing, on the border. Feel free to ask if you need better view of specific area  8)

More details regarding the disposition of the boards are available in the Galaxian≥ [Zolgear] Emulation part #1 : the boards (http://www.dragonslairfans.com/smfor/index.php?topic=457.0) post.

Let's start with :

1. PERSONAL PCB (3x)

Well the component side pictures are very difficult to reassemble...

Maybe this kind of picture may be more useful ?  :arrow:

Still not have a good camera (I'm using a poor Kodak M883), too much noise on the full size picture  :?

In order to have more help, I've also post a message on Mame World board (http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=204992&page=0&view=expanded&sb=5&o=&fpart=1&vc=1) to highlight the huge work to do here , and of course having as much help as possible for all the tasks to do (the list is big  :oops:) ...

Ok, regarding the question about taking pictures of the boards, get some advice from TheGuru : ... take the pics outside in sunlight but ensure there are no shadows on the pics. don't use a flash, you must do it outside in sunlight with no flash, perferably with a tripod so pics are in focus and bright...

The bad thing is ... my Kodak EasyShare M883 really suck, even if it's a 8 millions pixels  :oops: But, let's see what I can do.

Here's the setup :

(http://www.arcadelifestyle.net/G3/dragoon/Galaxian3_Kodak.jpg)

You can see the result, the pictures  for the Master CPU boards on this topic... not too bad, but not accurate enough (This cheap Kodak sucks, and not enough sunlight in Belgium  :evil:) BUT I'm sure with a better camera, like a Nikon D90, it will be perfect  ;) Of course, the only judge will be the Mame Dev who'll analyze these pictures  ;)

I've read one sentence this morning ... it makes my day  :-* :-* :-*  :arrow:

"I've also made some progress of CPU emulation from earlier this year. I've figured out the master/slave 68020 configuration, and made them communicate each other.
In my galaxian3 driver, the master 68020 has been able to upload many data to the slave. My code was based on MAME 0129u6. I'll do some cleaning up and submit it later."

Oh dear...  :o  :arrow:

(http://www.arcadelifestyle.net/G3/dragoon/galaxian3theater_palette.jpg)

The 2 68020 CPU boards has been able to pass many self test items(indicated by LEDs), and the master CPU uploads a lot of data to the slave, if given some patch/hack.

Among these data, there are:
DSP Code
Mathmatic Tables
2d sprite palette
Some test code
...
...

From the sprite tiles, the 2d palette seems extracted correctly.

I'm in love  :-* :-* :-*

Yay, it's on the fast track to emulation!

Does MAME handle most Laserdisc games well? I know 3D games are pretty demanding when it comes to CPU...

Yes, most of them are working good, but require powerful CPU.

I've just put the ultra high-def. pictures of a major board : THE BACKPLANE

This one was extremely difficult to scan because it's a bigger board than the other ones PLUS there is a big level difference between the components... so not easy to lay down on the scanner and keep homogeneous pictures  :twisted:. I had to scan FOUR areas... and reassemble it... no an easy task... but ... hey ... it's done!  :-* Crazy job, let me tell you...  :P :twisted:

This board is very interesting because if you look closer, you will see this one is able to manage itself FOUR PGN, DSP and OBJ boards! It can output up to FOUR different display devices (in that case, up to FOUR projectors).
The funny thing is a GT-6 (What we use to call 'Galaxian Theater') has TWO backplane!  :arrow:

(http://www.arcadelifestyle.net/G3/emulator/2ndbox1.JPG)

...so this 'piece' of hardware would be able to use up to 8 projectors! It's now clear that this backplane has been also used in the GM-16 model (Galaxian3 for 16 players), and maybe in the famous GH-28 (Galaxian3 for... 28 players!!! see here (http://www.dragonslairfans.com/smfor/index.php?topic=399.0)).

Cannot reply to this question yet, but I don't think there will be a lot of sounds... except fire/explosion sounds, menu sounds, insert coins sound... most (all?) of the backgrounds musics and voices seems to be on the laser disc footage... but who knows... let's wait some progress on this  ;)

What are the Lables/Models of these 2 ICs, on the C-RAM Board?
(The red circle on the right indicate some photoshop mis-aligns).

On the first picture, here's the ref for the IC located at 2J,2F, 7J, 7F on C-RAM PCB :

232782JAS
SN74S1057SC

What is the board on the second picture?

On the 2nd picture it's the CPU board. However, some other boards also have similar mis-align, on their slope-border.

Some tips I summerized for joining scaned pictures:
1. Make the join-border vertical or horizontal, instead of slope;
2. Noticed that most circuit on the CPU board's component-side are vertical, so scan it upper-and-lower, instead of left-and-right may avoid most mis-alignment.

I've downloaded your newly scaned CPU pitctures. They're pretty good. So you needn't re-scan them.
Have a nice trip!
