I would not know if it is possible, but the similarity does for sure make
it easier to emulate it. Of course you need to check all opcodes (IN's and
OUT's will be very different), but it is very fast if you can say: with
all these opcodes we can just execute the command directly. As I said
before, I don't know if it is possible to emulate it at reasonable speed
(It seems that it isn't), but it is a very good argument the cpu's are

Re: Would a GameBoy emu for MSX be possible?
Of course you need to check all opcodes (IN's and OUT's will be very different), According to the Gameboy technical specifications faq (to which Marat has contributed) the CPU doesn't even know port I/O instructions. Here's what it says about Z80 compatibility: Processor - The GameBoy uses a computer chip similar to an Intel 8080. It contains all of the instructions of an 8080 except there are no exchange instructions. In many ways the processor is more similar to the Zilog Z80 processor. Compared to the Z80, some instructions have been added and some have been taken away. The following are added instructions: ADD SP,nn ;nn = signed byte LDI (HL),A;Write A to (HL) and increment HL LDD (HL),A;Write A to (HL) and decrement HL LDI A,(HL);Write (HL) to A and increment HL LDD A,(HL);Write (HL) to A and decrement HL LD A,($FF00+nn) LD A,($FF00+C) LD ($FF00+nn),A LD ($FF00+C),A LD (),SP LD HL,(SP+nn) ;nn = signed byte STOP ;? SWAP r ;Rotate register r by 4 bits The following instructions have been removed: Any command that uses the IX or IY registers. All IN/OUT instructions. All exchange instructions. All commands prefixed by ED (except remapped RETI). All conditional jumps/calls/rets on parity/overflow and sign flag. The following instructions have different opcodes: LD A,[] LD [],A RETI Unfortunately, the document doesn't tell us which opcodes go with these mnemonics, but at least it gives some valuable info about the hardware of the GB. So pick up a copy of GBSPEC.TXT if you're interested. Or I could mail it to you if ou like. Pierre MSX Mailinglist.

(Silly) question about MSX on PC
Hi there! I am wondering if a MSX-emulator exists, that accesses a SCSI device at startup in the same way the MSX does. That it will execute MSX-DOS2 at startup, and will give me the opportunity to use eg. Multi Mente to read files and run MSX-programs, in the same way I do it on my MSX. Why? Because I have been using a 40MB SCSI harddisk on my MSX but since I got a ZIP I didn't use it very often. So I put it into my pc (because i needed some space on my desk, and there was plenty of space inside the PC cover). At my great surprise the pc can read the BERT partition table so I can acces BOTH partitions with my pc.. but since a 40MB harddrive is not very useful on a PC i thought: 'maybe a "fake-MSX" can use it'.

He didn't want to emulate his interface, he wanted to use his harddisk (the partition, not an image on it) as a harddisk which can be used in the emulator. There are two ways then: I mentioned that Windows NT could open a harddisk on a certain level that allows you to bypass the directory and file structure and read/write the harddisk as IF it where a diskimage. In this case the BERT SCSI rom would interpret the contents of the harddisk partition / diskimage. If you don't want an image representing a harddisk than you will probably want a certain directory on a PC harddisk to be interpreted inside the emulator as if it is a harddisk. The same could be done for a floppy, just put the files inside a directory and tell the emulator that that particular directory is to be seen as a harddisk partition or a floppy. In this case the emulator would interpret the contents and represent it inside the emulator as a harddisk or a floppy.

For instance, you can keep all GB CPU registers (including flags) in the alternate Z80 registerbanks permanently. The GB CPU PC and SP can be kept in Z80's IX and IY. Also Gameboy uses 16kB ROM switching, easily converted to MSX memorymapper switching. Also, other computers normally don't have patternmodes, MSX does. For V9990 it would be easy to store all patterns, this means hardware tile-caching! Even with SCREEN 4 it would be possible if you reduce colors per tile from 4 to 2. As a result of this patternmode, MSX doesn't have to build the entire screen every frame. And certainly not pixel-by-pixel, like PC's do! MSX also has the advantage of hardware scrolling and VDP commands. I'll immediately admit it wouldn't be possible to emulate the GB (let alone GB Color) perfectly on current MSX systems, but an 'approximation' is definately within the possibilities I believe. Even if it could run only 1 game at 10% speed, it would be impressive, right?! Greetz, Patriek ,--. ,---. ,--.
