0.153 [David Haywood, Se Yong Jang]
WIP:
- 0.153: David Haywood and Se Yong Jang added 'X2222 (final debug?)' (Oriental Soft 2000) and clone X2222 (5-level prototype). I've managed to build a newer version of the x2222 program from the TEST.HYE we were given. This version has all 7 levels and staff credits and the boss graphics are correct too, although seems to be a debug build (debug values are onscreen at all times). We still have no sound rom [David Haywood].
- 25th February 2014: David Haywood - Oriental Soft were a Korean developer probably best known for the titles 1945kIII and G-Stream 2020 (which was produced by Oriental Soft Japan). It is also one of the ancestors of Triangle Service who would go on to make titles like XII Stag and Trizeal. We (the MAME development team) were recently contacted by a se yong Jang, informing us that he was the main programmer of another Oriental Soft game 'X2222' and that he would like to see it emulated. We were forwarded several roms, including graphics and two raw '.HYE' hyperstone object files. For one of the .HYE files (an older, prototype revision) we were also supplied with a ROM binary. Unfortunately we don't know exactly how to convert the other .HYE file to a ROM binary and it seems the one we do have as a binary doesn't quite match the sprite graphics we were given. No Sound ROM was supplied either. The hardware, as it turned out was a variation on G-Stream. Much of it was the same, sprites, 3 layers of tilemaps etc. except for one critical difference. Instead of using 8bpp indexed graphics and a palette this game actually stores raw 16bpp RGB data in the graphic roms (meaning you can only have half as many graphics in the same space and can't do palette effects with them because the colours are hardcoded as part of the data). MAME can't handle 16bpp data directly with the regular drawgfx and tilemap functions so I had to write custom functions in order to render this data correctly. Eventually I got the game mostly working, there seem to be some sprite wraparound issues that need further investigation, but it boots and can be played. Unfortunately there's no sound due to the lack of any sound ROM. I'm assuming it's missing rather than it simply using some kind of YM chip, I should probably check tho. Furthermore the graphics for all the bosses after the first level are corrupt due to the mismatch between the program rom we're using and the sprite roms we're using, the tiles referenced by the program don't match up. Finally the code we're using is for a 5 level prototype of the game, after beating the 5th boss the game simply returns to the title screen. It's possible the .HYE file we haven't figured out how to convert is for a more complete build. Thanks to Se Yong Jang for his involvement in this, it will be interesting to see if a more final version turns up, or the correct sprite roms for this prototype build.
