fix: cite xm6g.exe 3.38 code for X68000 ROMs
Refs leaned on the PDF manual and pointed inside instructions. Each now names the loader, the system file table index and the init path in xm6g.exe 3.38. SCSIINROM.DAT is needed on the base model only, and RTC.DAT and the YM2608 ROM take their read sizes.

|
||||
|
||||
Machines emulated are X68000, XVI, Compact, X68030 and the 040turbo and
|
||||
060turbo accelerator configurations (xm6g.pdf p.3). System files are resolved
|
||||
beside xm6g.exe. A twenty-entry name table at xm6g.exe:0x140592350 holds them,
|
||||
against ten in Filepath::SystemFile[] (XM6 2.06 vm/filepath.cpp:472-483), and
|
||||
each path is built by copying the name, splitting it, and refilling drive and
|
||||
directory from GetModuleFileNameW, the sequence XM6 2.06 spells out in
|
||||
Filepath::SysFile and Filepath::SetBaseDir (vm/filepath.cpp:88-105, 172-186).
|
||||
The path is rebuilt from the module path on every load, with no configured
|
||||
directory taking part. Loading reads a fixed byte count and compares it
|
||||
against the count returned, so every min_size below is a floor: a longer file
|
||||
loads and its tail is ignored.
|
||||
System files sit in a twenty-entry pointer table at 0x140592350 (IPLROM.DAT
|
||||
first, STATE.XM6 last). Filepath::SysFile at 0x1404e76d0 indexes it, copies the
|
||||
name, splits it and jumps to 0x1404e7950, which refills drive and directory from
|
||||
GetModuleFileNameW, so every system file is read beside xm6g.exe and no
|
||||
configured directory takes part. LoadROM inlines the same sequence for index 0
|
||||
(0x1404fca8d-0x1404fcb52). Fileio::Open is 0x1404e7390 (CreateFileW) and
|
||||
Fileio::Load 0x1404e7200 (ReadFile, success only when the full count is read).
|
||||
|
||||
Two files are mandatory. LoadROM (xm6g.exe:0x1404fc9a5) leaves through its
|
||||
failure exit when the IPL read fails, and the CG read falls back to CGROM.TMP
|
||||
before failing the same way, which is the string "XM6 requires two ROM files,
|
||||
IPLROM.DAT file and CGROM.DAT(or CGROM.TMP) file." Nothing in the executable
|
||||
substitutes for either. The system options page probes IPLROM.DAT,
|
||||
IPLROMXV.DAT, IPLROMCO.DAT and IPLROM30.DAT with GetFileSizeEx and accepts a
|
||||
file only at exactly 131072 bytes (xm6g.exe:0x140428f80, size test at
|
||||
0x14042920a).
|
||||
LoadROM (0x1404fc990) takes a memory type set by Memory::ApplyCfg
|
||||
(0x1404fe390): types 1 to 3 are the base X68000 with no SCSI, internal SCSI or
|
||||
external SCSI, 4 is XVI, 5 Compact, 6 X68030 and 7 X68030 with the expansion ROM
|
||||
option on. It reads the IPL ROM, then the CG ROM, then the SCSI ROM, and a short
|
||||
ReadFile count fails the load, so every min_size below is a floor and a longer
|
||||
file loads with its tail ignored. Memory::Init (0x1404fc5d0) calls LoadROM(1) at
|
||||
0x1404fc669 and returns 0 on failure. VM::Init failing at 0x140471218 sets error
|
||||
state 1 (0x140471221), and the startup handler at 0x1404737a0 then shows string
|
||||
47002 or 42002, "XM6 requires two ROM files, IPLROM.DAT file and CGROM.DAT(or
|
||||
CGROM.TMP) file", with MB_ICONSTOP and posts WM_CLOSE. Memory::Reset (0x1404fd610)
|
||||
loads any other type on demand: type 7 falls back to 6 (0x1404fd682), and any
|
||||
failure falls back to type 1 (0x1404fd6bc), so a missing model ROM only loses
|
||||
that machine.
|
||||
|
||||
The options page (0x140428f80) offers XVI, Compact and X68030 only when
|
||||
IPLROMXV.DAT, IPLROMCO.DAT and IPLROM30.DAT have GetFileSizeEx exactly 0x20000.
|
||||
Three startup checks run from 0x1404738b5 through 0x140472860, each skippable by
|
||||
its option. The IPL check (0x140472a99) reads the IOCS date bytes at 0x1000a,
|
||||
0x1000c and 0x1000d of the base IPL and warns unless they spell 87/05/07. The CG
|
||||
check (0x14047296e) sums and XORs 0x1000 bytes at 0x3a800 of the font and warns
|
||||
unless they give 0xec and 0x84. The SCSI check (0x140501290) reads 0x2000 bytes of
|
||||
SCSIINROM.DAT (0x14050142d) and SCSIEXROM.DAT (0x140501599) and warns when
|
||||
0x1ff8 holds "XM6 ", the stamp of the XM6 Utility replacements (0x14050147c,
|
||||
0x1405015da). Each warning dialog (0x140487730) continues on OK and closes XM6 on
|
||||
Cancel. No genuine ROM is hashed anywhere in the executable.
|
||||
|
||||
XM6 Utility, published separately at the same address, synthesises CGROM.TMP
|
||||
from the installed Windows fonts and SCSIINROM.DAT or SCSIEXROM.DAT from the
|
||||
Human68k version 3.02 disk image HUMAN302.XDF, which it requires at 0x134000
|
||||
bytes (XM6Util scsirom.cpp:86-90). It stamps the SCSI ROMs with "XM6 " at
|
||||
offset 0x1ff8 and a version at 0x1ffc (XM6Util scsirom.cpp:243-245), and
|
||||
xm6g.exe reads both files back and tests that signature
|
||||
(xm6g.exe:0x14050147c, 0x1405015e0) to raise the startup warning that names
|
||||
these files as substitutes and discourages them. Nothing rejects the file, and
|
||||
no genuine ROM is hashed anywhere in the executable.
|
||||
bytes (XM6Util scsirom.cpp:86-90), and stamps "XM6 " at offset 0x1ff8 and a
|
||||
version at 0x1ffc (XM6Util scsirom.cpp:243-245).
|
||||
|
||||
SCSI ROM requirements follow the machine (xm6g.pdf p.17). SCSIINROM.DAT is
|
||||
needed by SUPER, XVI and Compact and by any machine set to the internal SCSI
|
||||
interface. SCSIEXROM.DAT drives the CZ-6BS1 external board, which is the only
|
||||
SCSI variant the SASI models can take. X68030 needs neither, its SCSI ROM
|
||||
being part of IPLROM30.DAT or IPLROM30S.DAT. IPLROM30S.DAT and ROM30S.DAT are
|
||||
a pair used only when Expansion ROM is enabled on the X68030 options tab, for
|
||||
ROMs patched for 060turbo (xm6g.pdf p.17).
|
||||
The Mercury Unit OPN (YMF288) samples its rhythm section from files. The fmgen
|
||||
and X68Sound engines read six WAV files named from a table at 0x1405c0090
|
||||
(0x1404ed610), and the ymfm engine reads ym2608_adpcm_rom.bin instead
|
||||
(0x140574eb0).
