Fixed the Events Manager properly without enabler hacks (the root cause was missing gestaltAppleEventsAttr which was removed at some point between TBXI 1.0 and 1.1). Additionally allows Mac OS 8.0 to boot successfully without ObjectSupportLib error (its init function would return error if gestaltAppleEventsAttr was not present). Therefore, reverted to the original patched enabler (with only version check patched).

All files are in MacBinary format.

    Mac OS ROM_1.7.1_patched.bin is TBXI v1.7.1 with the required patches to boot System 7.x and 8.0 (Program-to-Program Communications toolbox patched back in, gestaltAppleEventsAttr value set).
        If you have a tray-loading iMac G3, PowerBook G3 Lombard, PowerMac G3 Blue & White or PowerMac G4 PCI "Yikes", and don't care about USB mass storage support, use this to boot 7.x/8.x - as this still has most of the legacy implementations present and will have the least software compatibility issues.
    Mac OS ROM_2.5.1_patched.bin is TBXI v2.5.1 with the required patches to boot earlier versions.
        If you have an early Mac99 system (before circa 2001), or you care about USB mass storage support, use this to boot 7.x/8.x.
        USB mass storage support seems to only work on 7.x for devices plugged in at boot time - and booting from USB mass storage seems to not work.
        Has some PMU issues on Pismo, but booted fine on Lombard.
    Mac OS ROM_10.2.1_patched.bin is TBXI v10.2.1 with the required patches to boot earlier versions.
        Works on anything that can boot 9.2.2 without additional patching, and can boot from USB mass storage with no issues - but will have the most software compatibility issues.
    System Enabler 356_patched.bin is the CHRP System Enabler with the version check patched out such that it can boot System 7.5.x.
