X68000 core

Postby Sorgelig » Thu Nov 02, 2017 2:04 pm

I'm in process to port X68000. I know some users wanted it (including me).
Unfortunately most info is in Japanese. Most tools are also in Japanese. Even original core is developed by Japanese developer.

If someone is familiar with this computer, then any info is welcome.

core requires FDD image in D88 format.
you can use following converter to convert into D88: http://retropc98.narod.ru/soft/vfic.rar

For HDD image, you need to create a SASI disk image (SCSI is not supported!) up to 40MB in some PC emulator like XM6.

I know somebody who collects for this computer but he probably doesn't know about electronics much. If there is something you'd like to know about software or a game, I can try asking him.

I would like to get HDD image with graphics OS i saw somewhere.
Also would be good to have some interesting games for test. I didn't test audio yet. How good joystick is working - also unknown.

I want to be clear: only SASI images are supported. SASI is predecessor of SCSI.
Most images you see in internet are SCSI.
It's easy to distinguish: SASI cannot be bigger than 40MB. So, any image greater than 40MB is SCSI image.

according to code, RGB encoding on X68000 is odd. R5G5B6. Usually it's R5G6B5.
Is it true or is there something wrong in core?

Anything here : http://nfggames.com/x68000/Games/

NFG_HDD_images.rar = 3 * 40MiB files

My 'go to' place for old software is always The Internet Archive. And it usually never fails me. Even in this case, there is a TOSEC file: https://archive.org/details/Sharp_X6800 ... 2012_04_23 with a lot of games in it. If you search for X68000 most of the books are in Japanese, which doesn't help, but there may well be some useful information there.

X68000 suffers from graphics problems in games very bad.
It's more like proof of concept than replica.

All these changes are not related to graphic problems. I will wait till he will start to fix graphic glitches and then I will update my port. Until that the whole X68000 is kind useless. You don't want to sit in console with Japanese text. You want to play games, right?

I don't know. the name "1chip X68000" is similar to "1chip MSX" giving idea it may come from the same author as MSX.

Did you get any game to run? I converted few to D88, but none succeeded :-( My favorite is Chou Ren Sha, but I tried Gradius, Flappy, even HUMAN 3.0.2 did not start :-(

Set D88 image and SAVE by DISK EMULATION UTILITY. Reset core, then the program will start.
(Of course, this method is not normally :( )

I tried GRADIUS, but DEMO play halt, not loop.

This is what I tried, but no success. Could you, please, send me your Gradius Demo D88 file to my e-mail martin@8bity.cz ? I usualy end up stuck on messgae "The system could not be starated. Please reset." (in Japanese) or "X68000 terminal V1.0" message while booting the disk.

I saw the message "X68000 terminal V1.0" only once, but I could not understand the mechanism.
Terminal message is appeared by set debugger address to SRAM(SRAMU.mif/SRAML.mif). The value set for both .mif data. (pls refer: http://fpga8801.seesaa.net/article/418166041.html )

I have to say thanks to OhIshi. He helped me with config file and it looks like that it should countain HDF file even if you do not use it. I also removed SRAM file from it and now I am able to start Gradius, Flappy end even Cho Ren Sha. On the ohter hand, the games are really not playable. Well the Flappy is almost playable, but even there are graphics glithchces, no sound and everything seems to be slow. But it is a progress. Thanks.
