"Let's make GD ROM emulation happen" Facebook group.

So you've actually got it booting and running real games? Awesome! It's been a long time coming. Can you do a quick video?

 

IDE won't be a problem. :sneakiness:

I'm almost set up for that, and IDE is actually easier to work with than SD cards.

I have seen some 4-bit transfer code on the Web for SD though.
I know the full SD spec is supposed to be closed, but I'm sure I saw some code somewhere?

The newer Cyclone IV GX chips can handle SATA directly too.
I think we'll start with IDE / CF first though.

Well done cybdyn! :love-struck: :excitement:

I told everyone this project needed a fresh mind on it.
I'd tried to get it working for over two years, so I got more than a little fed up with it in the end.

Glad it finally seems to be happening now.

i plan make 4bit / sd mode for sd, but ... time)))

i made wires/connections for attach IDE device, but didnt test it. for HDD i plan use ide<>sata converter.

 

i made video.. good quality.. but size is big... no matter, i'll find the way to show it)

 

Fantastic news! Are you stuck in a place where upload speed is terrible too?

Do not remind me... Please do not remind me... I'd had the NBN Co boxes installed in our sub floor too...

 

actually, i dont know.. i need test game w/ video. crazy taxi and 18wheele were w/o video ??? or it was skipped?? ))) i dont remember. i played on DC 7..8 year ago or even more)))

 

Tony hawks pro skater 2 is a game that starts with sfd videos, if you need a test game!

Congrats on the advancement! Gotta put some money aside, so I can buy this right away once it's released!

 

Dino Crisis - works now. it has video. i'll try make video

it.s w/o video 18wheller: https://mega.co.nz/#!AkNgDaIB!M1b8yG7ecLxS3tai6ERqok_rWYlK1048SxM3p8suwTo

 

I don't think Crazy Taxi had FMV. Everything is rendered from what I recall, and every game I am aware of, using CRI middleware for FMV, so if you don't see CRI logo at game start - no FMV there.

EDIT: Resident Evil Veronica should be good game to try.

cybdyn, I think a lot of those vids are duplicates?

Do you have the Crazy Taxi one, I'd love to see that after all these years of working with the damned thing. lol

EDIT: Just an extra point - I don't think the "Copy to Clipboard" thing on Mega always works properly?
I sometimes have to manually highlight the link before copying it with the right-click menu.

btw, to any people thinking it's still slow - it's actually quite good speed already, and way better than SD card on the serial port.

Remember, the SD card transfer rate is quite a minor issue now that's it booting games.
It's not a problem at all to add CF card support to the basic design, but I think cybdyn may try some 4-bit SD controller code first.

Also keep in mind - this is running REAL GD RIPS!! :applause: :encouragement:

No more scrambling of binaries or evil boot methods needed! This is the real deal!

Once the code is finished / tweaked / perfected, it will parse the .GDI file text and generate the TOC info directly.
CD Audio support will be tricky, but I'm just very happy that it's booting games now.

Also, did anyone give thought to the fact that this emu could be made to work as a generic CD drive emu?
That means it could be used on PC's and many other consoles / arcade machines which use a standard IDE drive.

That will take extra coding ofc, but it will be interesting to try that with a SATA adapter at some point.

Yes the last link is from Dino Crisis not Crazy Taxi btw this is the real thing. This is realy good news.

also the sd card class 4 have write speed 4 mb/s so i dont think this is problem

 

I think a 4-bit SD card driver will make all the difference.

It's already loading fairly fast, and video is quite good too, so I don't think it will need anywhere near the GDD peak transfer rate of 16.6MB/s.

A class 4 or 6 card with a 4-bit interface should work great.

I doubt any of the video codecs run at much more than 3 to 4MB/s either, so should be working nicely soon.

Don't want to put any pressure on cybdyn though - still a lot of coding and debugging to do.

I want to try getting mine working too, but cybdyn deserves some profit for his efforts first.
(I will help with PCB layouts and getting them manufactured if I can.)

There's a LOT of work involved in this stuff, believe me.
Even when it's mostly working, there will always be improvements that can be made to the firmware etc.

As it stands, I'd expect that most "3-track" GDI's will work OK.
Support for games with lots of CD audio tracks will follow, but it might take a while to get that working.

Well I am awaiting this device more than any other retro-wise. The SD/Serial port adapter is terrible. Wonder how feasible to load games via the DC Ethernet Adapter ala PS2 can?

 

DC ethernet adapter is pretty rare, you should be really into video games to spend $150-$200 to buy it.

 

So my power fails for 24 hours, is still out, and I get online using backup generator power to find that DCIO is successful with games finally playing.

Totally made my day there.

 

!!!!!!!!!!

Yeah Cybdyn!! you made it!!
