I definitely strongly don't support pissing off gimons. You're welcome to develop your own accelerator and truthfully most people won't benefit from one in the first place.

The person who made that denies a software license to any but the original purchaser, so if a clone used his firmware it'd technically be copyright violation.

Some of you know of the existence of PhantomX CPU acceleration board for X68000 that uses Raspberry Pi and overclocks real machines but the problem is it is rather costly at 29000 yen but most importantly it hasn't been available to buy for a long time but I had an idea- how about reverse engineering it?

As far as I can tell this board is very simple- it only has a few voltage translators but it also has some GAL chips. However the firmware files are still provided right here:

So naturally I had somewhat of a dirty idea to just reverse engineer it because it shouldn't be hard for anyone to do. Well, personally I would but I don't have this board. Is there anyone that would be up for the task? All that is needed to be done is multimeter the chips and draw a schematic, that's it. Please let me know what you think about this

Hi,Guys.

i am quite new here but nit new to retrogames..in general.Lately i bought an x68000 XVI ..and i would like to buy a blue scsiV2.I am  reading and reading everywhere but i do not get what to do so.. i try asking here for some help(please😊):

- do someone knows what do innerd to to do with the termination and where (inside the X68000 mobo,i think🤔)

- For what the Blue Scsi guy told me the working version with the XVi,id the desktop one (internal installation right?)

- Which cable i need to connect the Bluscsi V2 desktop to the mobo?

- which kind of raspberry picondo i need to provide to work with bluescsi?
(considering that i am in Jaoan and buying it from Yahoo Jp)


- about the X68000 XVI: the external scsi connector is not a uusual scsi connector that i can connect with other scsi devices (do i need am adapter?)

- and what about the XVI internal scsi connector?..which kinf of adapter is required?

any particukar advice and/or weak/good points  compared to BlueScsi?


Sorry if they seem noob questions...but i am  an almost total noob about yhis great computer..so a "spiritual guide could ne apreciated😊)

rhanks in advance guys!

I think that might be right. I'm contemplating making a patch to let it load from directories instead but I haven't thought hard about it.

Super Hang-On is an interesting one. I actually have a pretty ok understanding of how that game works. Basically SHIPL.X checks for the presence of disks in appropriate drives then executes SH.X. SH.X has a fairly involved loader at the start that uses standard DOSCALL stuff to open, read, and close the files it wants and does things with them after that. Generally it doesn't do anything interesting or special in regards to files themselves and if you get the splash screen with the countdown it's already made it to running SH.X and has loaded at least one file off the disk so I'm kind of at a loss there too.

The key to the problem, may lie in the way 2hdsim booting works.

Its ideal boot environment so to speak.

I remember the same thing happening with Super Hang-On, it would complete the countdown but not launch.

When I copied it to the main partition in the Games folder, it would even complete loading long before the countdown was finished.

It just freezes, it won't continue loading.

I think the fact that they boot correctly on the main partition in the Games folder, like the old HDD images released before, indicates that the files are configured to see this partition as native.

If this is just a Henkan Bancho issue, it should happen with other titles as well.

Crazy stuff.

Nothing on screen unfortunately other than the copyright info. This happens with all versions I've tried other than the one on shoometsu's 030 image. That one gives an address error but I think it's due to being patched to run on 030 machines.

yeah thats pretty weird.

nothing really stands out to me immediately just looking at the disassembly.

does it print any messages on the screen or does it just hang? if no messages I'd probably need to run it in the debugger to get an idea whats going on. An awful lot of stuff happens between the copyright message and graphics being on screen.
