Tickled_Pink Posted November 9, 2017 Share Posted November 9, 2017 Well, there is this one. http://scpcd.free.fr/ But no idea if work progressed on it. The part he had been using is fairly low cost as far as I can tell. Quote Link to comment Share on other sites More sharing options...
Zerosquare Posted November 9, 2017 Share Posted November 9, 2017 It works pretty well, but hasn't been released. Anyways, the current version is an enhanced Jaguar with better specs, not a replica of the original ; and it uses an expensive Arria V FPGA (I don't remember which exact model, but it's likely more than $500 just for the FPGA alone). 1 Quote Link to comment Share on other sites More sharing options...
BeefMan Posted November 21, 2017 Share Posted November 21, 2017 Can't wait to run the Jag via FPGA with the bump in specs you mentioned. Hoping this will be something we can all run as the hardware continues to get cheaper. Quote Link to comment Share on other sites More sharing options...

swapd0 Posted November 22, 2017 Share Posted November 22, 2017 Since this is done from the original "netlist" files, it's 100% compatible with the jaguar? Quote Link to comment Share on other sites More sharing options...
Zerosquare Posted November 22, 2017 Share Posted November 22, 2017 Which one? SCPCD's project is not based on the original netlists, it's a complete reimplementation from scratch.You'd have to ask him, but I don't think he intends to release it publicly. Torlus' project is a port of the original netlists to an FPGA and is public, but I don't think it ever went beyond the incomplete proof-of-concept stage.

swapd0 Posted November 22, 2017 Share Posted November 22, 2017 I asked about Torlus project, anyway it looks that it needs a big FPGA, I was wondering if it can be ported to the MiST. Quote Link to comment Share on other sites More sharing options...
Torlus Posted November 22, 2017 Share Posted November 22, 2017 Hi, There is no way that it could be ported to the MiST. Aside from the FPGA capacity, the main issue would be the 64-bit data bus. The board I used for this purpose is a decade old Stratix-II evaluation board found by chance on eBay, coupled to a custom daughter board for VGA output. The main advantage of this board is that it features a 32-bit SSRAM, which was convenient. Starting from the original netlists guarantee that Tom and Jerry chips are 100% exact. However, the remaining parts may not be so accurate. But it should be quite easy to fix, especially by someone that knows the machine, like SCPCD. Now, it would be nice to find a board that features all the required parts (maybe a DSP-oriented FPGA board), and cross fingers for the price tag.

Newsdee Posted December 15, 2017 Share Posted December 15, 2017 Aside from the FPGA capacity, the main issue would be the 64-bit data bus. The board I used for this purpose is a decade old Stratix-II evaluation board How about the MiSTer? It uses a Terasic DE10 Nano Kit board with a Cyclone V with 110K LE, plus an extra 32MB of SDRAM.https://github.com/MiSTer-devel/Main_MiSTer/wiki In any case both boards are a nice home for your other cores Genesis was upgraded with sound and more memory mappers were added for the PC Engine.

youxia Posted February 21, 2022 Share Posted February 21, 2022 For the record, the @Torlus's core has been actually ported to MiSter long time ago. You need two SDRAM sticks to run it, but it got to the stage where it's somewhat usable - games load, and are playable, but most crashes sooner or later. It hasn't been worked on for a long time, but now another dev, @Kitrinx is apparently looking at it too. So maybe we'll get two Jags eventually (thing with Jotego is that he releases betas of his cores for Patreon supporters first, so it might take longer). 1 Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted February 21, 2022 Share Posted February 21, 2022 I'm especially excited as there's not enough room for the Jag in my office. Got a Jag Studio "Hello World" to compile and run on a core found on YouTube. But, most games and other code examples just don't run. Hope it doesn't use two sticks as I bought a generic pre built setup with just one. Don't feel like potentially breaking the thing to try fitting an extra stick in there somehow.

This year? That guy looks like he has a 100 things on his plate and this just added another 20 to his list. Maybe he'll do some kind of Jag beginning this year but wouldn't hold out hopes for anything we can use for a long while.

I read that coders did no even dare to use Jerry for anything but sound ( so not like the second SH2 in sega consoles virtua fighter games ) because it was all so difficult to use. So most games should not stray too far from the official path and not depend on cylce precision like C64 games or later N64 . 2 Quote Link to comment Share on other sites More sharing options...

Nobody says it'll be here in 2 weeks. But it's certainly nice to hear that an experienced dev (in fact, two separate ones) is planning to do something about a machine which so far had only an experimental, rather unusable core, lying dormant for 2+ years. Especially seeing how blazing fast PSX development is...it went from nothing to actually playing some games fine in space of a few months.

Who is the other? Hopefully we'll see something working in n a decent time table but that guy seems so overloaded and everything else he's working on is in way more demand.

melrocks Posted February 22, 2022 Share Posted February 22, 2022 The Jotego implementation will be superior. The other developer, while semi-competent, has yet to prove they can develop a core from the ground up. All of the work done by them has been only fixes and tweaks for the most part.

Kitrinx got the 7800 core to a development worthy state and even brought in 2600 support. I'm betting she gets to the Jaguar first. 2 Quote Link to comment Share on other sites More sharing options...
KidGameR186496 Posted February 22, 2022 Share Posted February 22, 2022 What I'm interested the most is seeing who will be the first to make both Iron Soldiers and Hover Strike playable on these FPGA setups, given that they can't be played on emulators like Virtual Jaguar and Phoenix. 2 Quote Link to comment Share on other sites More sharing options...

I guess it's one of the few systems with the netlists available that can be translated to fpga? So maybe it will move along quickly. 1 Quote Link to comment Share on other sites More sharing options...
