Well, I can't actually tell what I think about TimewARP 2600 because SONiVOX didn't accept the redemption code I was sent by KVR and although I requested help on Sunday, 15th September 2019, I got no response yet (2019-09-22T17:08:30).
On 31 Dec 2016, I bought Timewarp 2600 as part of a very attractive bargain on on SONiVOX Premier Collection Upgrade from PluginBoutique. (SONiVOX sells Timewarp 2600). Unfortunately, I cannot save my user patches. Every time I try to enter a patchname, I get this error message: "Unacceptable character. You can only type a number here". So I cannot actually save any patches within the VSTi itself. Anyone had this problem and know the solution?
I purchased it the same week, but didn't manage to find some time to install the software. Today I found your message here, and tried it. I can not confirm it. Here it works well (Reaper v5.32, Windows10) - to my surprise it did not crash, as Windows 10 is not officially supported. A little bit confusing that they put software for Windows 10 with software for Windows 7 in one bundle. The Big Bang crashed immediately after I tried to play it with a MIDI controller. Standard support answer that I got was: Windows 10 is not officially supported (it is just for Windows 8). But there's a workaround for that problem that the support did not know as well: In Windows 10 it is possible to launch an app in Windows 8 compatibility mode. Maybe try that... hopefully it solves your issue, too.
