Don't worry, there's lots of stuff I don't understand either :D. But it's so cool to see the components I've interacted with last year with my own...

Hi, long time no see :). Just mentioning I've updated the wiki of my research on the SVP with a new page with images of a decapped SVP and some...

Hi! I've spent some time these past few days researching on what the test code inside Virtua Racing does. Here's my wiki page for that (which I...

Hi! I've spent this weekend researching on timings, one of the less known areas about the SVP. I've managed to measure how fast IRAM runs against...

Hey, you need to trim the spaces in the file at the beginning of the generated binary (because of the ORG 0xFC00 directive at the beginning of the...

Hey, thanks for giving it a try! I was assembling the BIOS code with the installed version and I hadn't try with 'cargo run', which runs in debug...

Oh sure! That's the SHA-1 hash: 0b951ea9c6094b3c34e4f0b64d031c75c237564f I've added to the wiki too for reference. Thanks!!

Hopefully that's the case! It's a shame something like this was "hidden" in plain sight and no one seemed to know about it. In any case, anyone...

Hi! I've updated the previous link (https://github.com/jdesiloniz/svpdev/wiki/Internal-ROM) with the full disassembly of SVP's internal ROM. I've...

Another follow-up post: I'm starting to document the disassembly of the internal ROM within SVP here, in case anyone is interested on taking a...

Could be, but the chip doesn't seem to shut down, it just enters an infinite loop. Haha i didn't notice that was you over there! That thread set...

I'm a bit wary about sharing the binary, but my idea is to share the disassembled code (that you could create your own binary too). I mean, I...

Well, it turns out that the SVP has an internal 2KB firmware, apparently only accessible from the SVP side (I haven't tried it yet but I don't...

@PhyChris I had zero doubts about it but yeah, a normal game works with the SVP! (I uploaded a video of Sonic 2 running on it on the Twitter...

Wow thanks @rata! I'm really happy as this is probably my first hardware project that works! (considering that my previous attempt with the SVP...

Well, here's the ROM that I mentioned the other day running on a real SVP! [img] Also Virtua Racing running correctly from the external EPROM:...

I'm still waiting for the hardware boards that I need to see if I can get custom code running on the real SVP, but as it's taking a while to...

@PhyChris yeah, the dump I got directly from the ROM chip was byteswapped :)) I've already written a small tool to do that (and splitting the...

@PhyChris Hahaha thanks!! I think A19 (B7 in the cartridge right?) is connected to pin 160 in the SVP chip in the prototype picture (and also in...

@PhyChris yup! That's on my plans as soon as I verify that the EPROM approach works (mainly because it's a pain in the *** to erase them lol)....
