This board is what the Atari Jaguar should have been as the Motorola 68k would stall the bus with it being externally 16 bit. A true 32bit 68020 would have greatly improved overall performance of the system.
@@robertfoxworthy5503the blitter does the DMA. And I tried to do the maths, and it seems like a cache would not merely mean a small circuit which loads addresses and data from scratchpad memory, but a dedicated small RAM with sun cycle access time. When you plan to compile C to JRISC anyway, why can’t the compiler insert instructions to load blocks in advance. Just ugly that we have to adjust all jump target addresses manually like the DOS exe loader. With clean code each function should only be 10 lines. So no need to split it. Just one call to the blitter. Relative addresses also work.
@ArneChristianRosenfeldt the dma is buggy broken from what I hear. I read interview with the system designer he said it originally was supposed to have 68020 and with Tom and Jerry clocked at a faster speed. Carmack did interview said he would have ditched 68k for another Tom. And to use a cache instead of scratch memory. And add a cache to the blitter. I read people on forums talk about wanting dma and cache. I think it's interesting.
A stat that always tickled me. Back in '93 they quoted the Jaguar as moving 512 million pixels per second. A couple of years later, it turned out that was only possible on a black and white TV. Just a fun way in which specs coukd be exaggerated.
If no one was willing to adapt the PS1 core for arcade games I'm not seeing this happening sadly. That big white connector is called a Eurocard connector.
Interesting video. Area 51 may not have saved the Jaguar, but it saved Atari Games financially, allowing them to have a brief renaissance period with stuff like the Rush series, Wayne Gretzky's 3D Hockey, and Gauntlet Legends.
Would be awesome to see what the R3000 based board could pull off graphics wise! I have a CoJag board - Maximum Force, is the single PCB but also appears to have room for more RAM, my understanding is most games on this particular Platform simply streamed FMV for the background visuals, looked into a possible conversion attempt to Vicious Circle but don't know know of any successful conversions.
I really want to see the IGS PGM to be a core to MISTER. I don't think it is possible but I want to see more of the later CAVE boards to be in MISTER like Deathsmiles BL, Mushihimesama, or Mushihimesama Futari BL
I just added a second RAM stick yesterday to try out the Jaguar core. Thanks for the setup videos! I did notice that my go-to, Wolfenstein 3D, is not quite full speed, at least on my setup. Is it likely that the core will reach full speed or is this simply the limit of MiSTer?
@@VideoGameEsoterica Whouaou, I didn't imagine that ... developpement on Jaguar was hard enough, I didn't think devs are porting their games into arcade version from Jaguar ...
Got a few of those boards here but the different version with Hi and lo roms... there is a maximum force duo conversion which also removes the need for the security chip... so if ur getting hardly anything then that will be it. Yes loads of boards with JAG chips.... also we just made a kasumi ninja arcade machine that will be runing on a pc emulator which was pretty good
The amount of knowledge you have on retro tech is so awesome. I imagine every closet in your house is overflowing with gear, lol.
Yeahhhhhh…maybe 🤣
@@VideoGameEsotericaSomeone has to do it, you're preserving video game history in multiple ways!
I do what I can :)

Atari tried to save money. Classic Atari move
@@VideoGameEsoterica Indeed
@@VideoGameEsoterica save money and cripple the system as the the 68020 had dma and a cache. The two things jag lacked

Haha oh yeah specs back then were massaged to the edge of the truth
If no one was willing to adapt the PS1 core for arcade games I'm not seeing this happening sadly. That big white connector is called a Eurocard connector.
But I’m willing haha. And others are as well
@@VideoGameEsoterica My intuition tells me it shouldn't be written in netlist and the core should be remade in a better way.
Someone would want to have to do that is the real issue
@@VideoGameEsoterica Good point
I have one spare Atari Jaguar board and it has been definitely much more interesting to study than most console -boards.
It’s always fun to poke around
Interesting video. Area 51 may not have saved the Jaguar, but it saved Atari Games financially, allowing them to have a brief renaissance period with stuff like the Rush series, Wayne Gretzky's 3D Hockey, and Gauntlet Legends.
Yes it sold well and generated tons of cash
True story the Atari Jaguar plastic mould was repurposed for use in hospitals
Yep. As an x-ray machine
Am I understanding correctly that Area 51 (one of my favorite shooters) ran on some sort of Jaguar arcade board? I never knew that.
Haha yep. Jaguar with a Motorola 68020 vs stock 68000
Yes
really cool to see the board. camera seemed like perfect footage. like that not dead yet comment on the schematics. funny.
Glad someone finally commented on the footage haha
Wow, didn't even know that existed. Thanks man
That’s what I’m here for :)

I’ve never seen a Vicious Circle conversion either now that you mention it
Direct sunlight will erase EPROMS in about 3-12 months, and that's sitting outside in direct sunlight in June the entire time.
Still important to cover them

Those sadly won’t work. The SH3 is clocked high and beyond what will work
@VideoGameEsoterica What about IGS PGM?
@rxzero00 should work fine. Will have a vid on it shortly

It’ll get to full speed eventually I’m sure
I got really into that game myself, only to realize that SRAM hasn't been implemented yet, hehe.
Haha yes you gotta 1CC everything
It's Caturday! 😻
The second best day of the week after 3DO day! (Watch the 4pm video. Get hyped)
R•E•A•L•Day incoming!? O_O
Four hours to go!
New camera footage looks good, though the (c) 2023 at the end is a tad anachronistic....
Haha grabbed the wrong resource file
Videogame S OOOOOOOO Terica!
I’m glad it’s become a channel meme. I do think it’s funny new people don’t realize it
@@VideoGameEsoterica I love it! Camera looks good too.
Glad some people are commenting on the footage. I figured even telling people nobody would really notice
@VideoGameEsoterica Yeah. I only paid attention because you mentioned it.
There is an arcade jaguar version ??
Yes the Jaguar got turned into an arcade board which you see here
Yes
Alot of consoles have Arcade versions, NES, SNES, Genesis, PSX, N64, Game Cube, Dreamcast, All had versions of their hardware made into Arcade boards.
@@VideoGameEsoterica Whouaou, I didn't imagine that ... developpement on Jaguar was hard enough, I didn't think devs are porting their games into arcade version from Jaguar ...
Yes almost every console got an arcade variant

Haha Kasumi Ninja. That’ll be a janky fun one
Jaguar was my first big disappointment in my life. After that it was just downhill
😂
Haha you learned what failure meant
If you still have one today then you’re making a comeback!
i completely understand that. i purchased my first Jaguar about two years ago and wasn't disappointed at all. big difference in time!
