Null DooM running on the 圆8000 DooM comes to lifeįrom there, Neko68k was able to do something amazing, add in system support! Which to be honest would have taken me forever to do, I was more impressed that I was even able to get the null version running, but Neko68k blew me away with this: I could then get from failing malloc to this: Once when he shared his disk image, I was able to see how his GCC setup worked, and more importantly linked, so I could alter the GCC cross compiler I was using, and get much further in terms of progress. I wasted some time by trying to bypass the Sharp LIBC malloc function by calling the HumanOS’s malloc directly which did get further but ran into issues when switching from usermode to supervisor mode to directly access the hardware. Over on nfggames Neko68k had mentioned that he had a disk image with a working version of GCC, that uses different includes/libraries that was able to get further. Starting the actual port aka platform issuesįor some reason the SHARP/Hudson LIBC has issues doing a realloc. After it was running with minimal changes, it was time to start the real fun.

I figured that by having a ‘known good’ build with the a very close compiler level would be a good start as I don’t want to fight too much with the compiler. Having learned the ‘null’ lesson of Quake 2 the hard way, I started out with a working copy from Windows, via GCC 1.40 for Windows/RSXNT. To convert C++ comments to C is quite simply:Īnd away we go. The key thing is the configuration file that tells uncrustify what to do. Uncrustify.exe -replace -c 1.cfg cl_main.h The pain is that it doesn’t seem to take wildcards, but you can use make to have it do your work for you, or just a batch file… In order to convert the comments, I came across this great tool, uncrustify. So the first phase was to convert all the comments.

Since I’m using such an ancient version of GCC the first stumbling block is that DooM is FULL of C++ style comments, which older K&R & ansi based compilers of the late 1980’s simply cannot handle. One platform that mysteriously was lacking DooM was the SHARP 圆8000.Īfter a bored day of playing with the source to Mariko’s GCC 1.42 / 1.30 that targets the 圆8000, I thought I would take a stab at trying to compile DooM.

And thanks to it being written in C is also an incredibly portable game.

Its unknown how many X68000 units were sold in total during its commercial life span.DooM is without a doubt one of the most popular PC games of all time. Originally released at JP¥369,000, later models were sold for considerably lower prices.

Games were also distributed through the Takeru software vending machines, which allowed users to write commercial titles or dōjin soft on blank 5.25" floppy disks. Multiple revisions were later released that included several enhancements compared to the original model, with the last model being released in 1993 before being officially discontinued in the market, though games for the platform kept being created.

Many add-ons were released including networking, SCSI, memory upgrades, CPU enhancements and MIDI I/O boards, among others that increased the performance of the system. The following list contains all of the known games released commercially for the X68000 platform.įeaturing an operating system written by Hudson Soft called Human68k and bundled with a conversion of Konami's 1987 arcade game Gradius as the pack-in game at launch, the X68000 was very similar to arcade system boards of the time in terms of hardware and served as the development machine for Capcom's CP System. It was the second and last computer to be released under the Sharp brand, succeeding the X1 series. The X68000 is a fourth generation home computer developed and manufactured by Sharp Corporation, first released only in Japan on March 28, 1987.
