Opera 10.63 Windows 95 Fix

Overview

Under Windows 95, Opera 10.63 does not normally run out of the box and gives an error about missing exports of DuplicateTokenEx, InterlockedCompareExchange, and/or GlobalMemoryStatusEx. However, with simple hex editing and UPXing, it is possible to run Opera 10.63 under Windows 95 (tested on OSR2, unsure if works on Gold or OSR1). Credit goes to Andrew T. from the MSFN Forums who initially posted the trick.

Note: DCOM95 1.3 (search for "dcom95.exe") and Windows Sockets 2.0 (search for "W95ws2setup.exe") are required to run Opera 9.5 and later under any version of Windows 95.

Instructions

• Install Opera 10.63 using the classic installer
• Download UPX in order to uncompress opera.dll
• Extract opera.dll using UPX
• Open opera.exe in a hex editor (such as XVI32), change references to "DuplicateTokenEx" to "DuplicateToken"
• Open opera.dll in a hex editor, change references to "InterlockedCompareExchange" to "InterlockedExchange" and "GlobalMemoryStatusEx" to "GlobalMemoryStatus"
• Note: add null characters in order to terminate the string and maintain its original length
• Optional: Recompress opera.dll using UPX (not required, but recommended)
