Look what my DC started displaying...(ok, so its TG16/PCE)

SDL to PVR is rather easy as long as all the emulator is doing is rendering to a graphics buffer and blitting that as an SDL surface. All you've gotta do is create a PVR texture that's big enough to hold the TG-16 resolution, which is 256x224, right? So you make a 256x256 PVR texture, copy from the intermediate buffer to the texture's address in video memory, then use the PVR functions to draw a couple of triangles correctly mapped with the texture.

yea, i think i have all the functions right, but that either the triangles are the wrong size, or i dunno. right now all i get is black screen =P

and i keep on crashing my DC =P

"idle task is the only thing left; exiting"

i've never hard crashed my DC before with anything ive worked on lol.

From what I've seen, all the CD units added a 16Mhz 65802. I thought the hardware differences between CD units was primarily in the amount of memory? Or was the second version of the CD system the first to include the 65802?

I'm not saying that version X of the CD system didn't have it, I'm saying that I don't think it needs to be emulated in any case because it seems to only be implementing a SCSI-like protocol and doing internal housekeeping operations for the CD system. That is, it's an implementation detail and not a program-visible feature, and therefore doesn't need to be emulated any more than you would need to emulate the individual logic chips used in the gamepad.

tg16 is my fav system outside of the dc... keep up the good work! A port with sound would be awesome! I can supply "various games" if anyone needs any when the emu comes out. The roms are Le4gUL so it's ok to post about them.

Quzar, you kick much ass! I haven't checked in the DC Emulation boards in a while, I pop in for a look and I find this wonderful piece of news. For the last week or so, I was pricing used XBox systems to play my Turbo and PC Engine CDs on. Fantastic job, sir. By the by, how about DC-Engine for the name of the emulator?

Ex-Cyber · Post by **Ex-Cyber** » Fri Oct 22, 2004 5:48 pm

"DC-Engine" has a ring to it, but was thinking "HUcast" had more of a DC geek factor to it.

rbenchley · Post by **rbenchley** » Fri Oct 22, 2004 6:08 pm

I prefer DC-Engine, but HUcast is pretty great. I would change the intercapping so it reads "HuCast", so its closer to the name of the CPU, the HuC6280 and HuCards. When Quzar decides on a name for his wonderful emulator, I would really like to make some CD and DVD case covers for it. Man, I am psyched for this! For the last month or two, I've spent almost all of my game playing time on Magic Engine on my computer. The PC-Engine is the epitome of wonderful, Japanese crafted games. Quzar, if there is anything that I can do to help, do not hesitate to contact me.

i know i listed the names i was kicking around somewhere, but now i cant find it =P. HuCast! was on the top of that list not only because it goes with HuGo! (to a recognizable factor) but also because it is reminiscent of bleem!Cast. Maybe Hu!Cast =P.

BTW, can someone teach me on how to run a cd on Hu-Go (dracula rondo of blood), that emu is harder than magic engine to use. but i want a windowed emu, and ME is way too dos like to me

The name ideas are coming out great... Hey DCMad, I'm from Brazil too... Mais especificamente, de Recife!

Post by **Quzar** » Fri Oct 22, 2004 6:28 pm

if you use the windows version you have to downoad gtk (there is a link on the Hu-Go! site) and move all the files into the Hu-Go! directory. elsewise you have to use the DOS version of it.

Someone would like to have a word with you about that.

Seriously though, HuCast does look better. My main concern with that name, though, is that it wouldn't be Google-friendly because of the PSO overloading.

@quzar: Has Hu-Go any kind of region protection on games? I've came across a program wich catalogs, rename and check for region hacks in roms. So i thought if the emu could refuse to load a jap game, lets say. Just like GenPlus does in preview3.
If there's something like it, how hard would be to overcome?

I was starting to get used to huZar name

@GustavoSM: Oi, parceiro. Vc vai ver que tem muitos brasileiros aqui nos f?rums da dcemulation e outros. Seria legal ter f?rums pr?prios por idiomas tambem, como os da gamefaqs. Mas enquanto n?o h? nada disso, qualquer d?vida quanto ao idioma, n?o tenha medo de perguntar, via PM.

Post by **Quzar** » Fri Oct 22, 2004 6:47 pm

if you google "Hu-Cast!" it doesnt give you that, but most people wouldnt care to do that =P.

Good source of information in PCE games i just found: http://pcecp.com
Many specs for the games, nice interface. Pay a visit.

Has Hu-Go any kind of region protection on games?

PC Engine has a couple protection mechanisms:

1) the HuCard data lines are reversed between Japanese and non-Japanese systems - this is why an adapter is required to play Japanese HuCards on non-Japanese systems.

2) There is a Japan/non-Japan territory register. Supposedly Japanese games do not check this, but most American games do. This is similar to the territory mechanism on NGCD and Genesis - the game can theoretically do anything with it, from changing the language to refusing to run - but apparently American games will typically not run on a system with a Japanese ID.

The emulator itself has no region protection, nor does the CD system (beyond the fact that the system/arcade cards must be wired/bitswapped properly). It may be possible that region detection doesn't always work, but I think there are commandline options to force a particular region.

the emulator is supposed to have rom cataloging ability, but for some reason it seems it needs hard drive space to do so becasue it stores all the info in some huge .dat file. This really does nothing but allow the emulator to put the name of the rom up, except with SuperFX games (i THINK) considering though that is all of 5 games its not really something I'm thinking about ATM.

dreamcastninja · Post by **dreamcastninja** » Sat Oct 23, 2004 1:19 am

you could call it

HUcast for the DC-ENGINE platform. hahahaa
OR

PCE-Dream

i dunno

it's late and i'm tired

going to sleep

*this has been a useless post from your's truely, i try to keep these to a minimum

Hmm, names for the emulator? You could call it TurboDuoDC
