Technical notes

Multi-machine Sinclair emulator. Every ROM is read from disk at run time; none is compiled into the binary. rom_load (src/cpu.c:3158-3751) maps current_machine_type to a filename through a switch, then resolves it with find_sharedfile (src/utils.c:1310-1348), which searches the current directory, ../Resources/, INSTALL_PREFIX/share/zesarux/ and the directory holding the binary, in that order.

ZEsarUX ships these files and installs them next to the binary: src/configure:1909 lists *.rom, zxuno.flash, zxmmcplus.flash, tbblue.mmc, pcw_8x_boot*dsk, mantransfev3.bin and alternate_roms in COMMONFILES. A normal install therefore already carries every entry below, which is why they are marked bundled: true.

A missing machine ROM is not fatal: rom_load logs an error and returns (src/cpu.c:3420-3428), the panic having been removed deliberately. The machine then runs on uninitialised memory, so the ROMs the switch names are marked required for the machine they serve. The one hard failure is prism_failsafe.rom, which prism_load_failsafe_rom loads through its own path and which calls cpu_panic when missing or short (src/machines/prism.c:581-590).

The emulator verifies no hash on any of these files. It does check size: the machine ROMs are compared against get_rom_size (src/utils.c:3514-3588) and the interface ROMs against their own *_ROM_SIZE constants, with a mismatch logged as an error. validation: [size] is set only where the code makes that comparison.

--romfile (src/start.c:998) overrides the machine ROM with any file the user picks (src/cpu.c:3410-3413); the ROMs under alternate_roms/ and the extra variants in the install root exist for that path and are documented in the shipped src/ALTERNATEROMS file. Interface ROMs are equally overridable (--divide-rom, --divmmc-rom, --dandanator-rom, --ifrom-rom, --kartusho-rom), and each falls back to the bundled default named here.

ES-DE drives ZEsarUX for its zxnext system with --machine tbblue --tbblue-fast-boot-mode --enable-esxdos-handler. Fast boot swaps tbblue_loader.rom for 48.rom (src/cpu.c:3263-3264), and the esxdos handler needs the divMMC firmware esxmmc085.rom, so that path loads 48.rom, esxmmc085.rom and the tbblue.mmc card image rather than a dedicated Next ROM.

ZEsarUX also loads UI and bundled-software resources through the same find_sharedfile path: keyboards/*.bmp on-screen keyboard art (src/menu/menu_items.c:19210, 21731, 21752), z88_shortcuts.bmp (src/video/screen.c:11078) and the my_soft/ homebrew collection (src/menu/menu_items.c:32146, 32205; src/menu/menu_items_storage.c:582). They are application resources rather than system firmware and carry no entry below. PrismChime.bin sits in the source tree but no code reads it and COMMONFILES does not install it.

• Size: 16.0 KB
• Validation: size
• Source: src/machines/prism.h:61, src/machines/prism.c:581-590, src/cpu.c:3536
• Loaded straight after prism.rom by prism_load_failsafe_rom(). The only ROM whose absence is fatal: the loader calls cpu_panic both when the file is missing and when the read is not 16384 bytes.

zxuno_bootloader.rom required in repo bundled

• System: sinclair-zx-spectrum
• Size: 7.9 KB
• Source: src/cpu.c:3243-3244, src/cpu.c:3486-3490
• Size note: Read caps at 8192 bytes and only errors when fewer than 1 byte is read, so no exact size check. get_rom_size returns 214 for ZX-Uno (src/utils.c:3534) but that value is unused on this path.

zxevo_tsconf.rom required in repo bundled

• Size: 64.0 MB
• Source: src/menu/menu_items_storage.c:12144-12155, src/configure:1909
• Size note: 64 MB, so it needs storage: large_file once the image is acquired and uploaded as a release asset.
• SD card image carrying the Next system software. Assigned as MMC card 0 by the local-tbblue menu action; the emulator reports 'tbblue.mmc image not found' when absent.

• Validation: size
• Source: src/cpu.c:3338-3340, src/utils.c:3562

• Source: src/cpu.c:3379-3380, src/cpu.c:3719-3728

ql_jm.rom optional in repo bundled

• System: sinclair-ql
• Size: 48.0 KB
• Source: src/cpu.c:3383, src/start.c:998

• Source: src/cpu.c:3350-3352, src/cpu.c:3675-3685
