Yes, the byteswapped hex should be fine with the GQ-4x4 and NAOMI 2. I have this exact setup, albeit the older GQ-4X. This hex will allow both netboot and CF loading (ABC.BIN) on NAOMI 2 with Net DIMM jumpers set accordingly.

Hey Hokuto. It’s been a while since we looked at those. I’m not sure if Leo still does decrypts, but my preferred method of revival nowadays is to restore the security keys, ideally fitting an InfiniKey CPS2 or an OpenKey CPS2 rather than a new battery. Doing this is far less work than...

I have them. Bear with me and I’ll upload and provide a link. Okay, have at it: https://archive.org/download/aw2naomi

You mean this old thing? I’m sure the case moulds are long gone. Towards the end, Capcom were just using up their inventory. They clearly stopped producing new cases, which is why we ended up with Japanese region B-boards blue cases, and Mexican region B-boards in all of the colours...

Good question! I was going to look into it… I only went the PIC route as I had a load of old chips which used to use for PS1 mods and I wanted something to mess around with during the pandemic. I would still consider doing a version for non-CN9 boards, but I’m not sure if there is much point...

Okay guys, thanks for your patience. Here are the Gerber files for the PCBs (I used PCBWay with good results), and the hex files for the chips. There are two PCB layouts: idc-CPS2_PIC12F509_629_675_683_DIP_konosuke_pinout_v4_gerber.zip - this follows the same pinout as konosuke's excellent...

Hi all, just to point out that during the CPS2 security reverse-engineering project, Eduardo reported that it’s regular SRAM which holds the security data. It’s hidden alongside the 68000 CPU in Capcom’s custom DL-1525 chip. SRAM is not subject to wear like flash RAM is. It is not harmful to...

I love the InfiniKey-CPS2, I have them in many of my boards. I know the feeling about being busy with life… In light of the scarcity of Undamned product, however, I went with a PIC12 solution. That, and I was trying to keep myself occupied during the second and third COVID-19 lockdowns of 2020...

Just for graphics chips. When SF2X was produced, larger capacity mask ROMs were either unavailable, or cost-prohibitive. Capcom used smaller capacity chips in greater number - more than the standard B-board can accommodate alone - hence the daughterboard. “G” PAL games are later games with the...

You don’t need the ROM daughterboard for conversions done in this manner. If the game is already running, albeit with phoenix ROMs, you just need to write the encrypted ROM images to chips 03 to 09, then install the InfiniKey.

Bit of a necrobump here, but oh well... The MAME docs in this case mean that the TED2 (export) dongle is not dumped, not the DVD. Or rather, the TED2 dongle has been dumped - twice it seems - but for some reason the files have not been released: http://database.trurip.org/st/st43-50 If anyone...

Bought a couple of System 246 dongles from @ArcSys101. Great communicator, fast shipping to the UK. Pleasure to deal with. :)
