Due to server slowness, downtime, and other issues, guests can no longer search the forum or view user accounts. At some point in the future Eclipse will be moving to a more stable and efficient platform that should result in much better stability and the lifting of these restrictions. There is no timeline for this yet, just want you to know what's happening with all the downtime and I have a plan to fix it.

Thanks for the info, but I prefer not to alter system files. So otvdm does what I need, mainly playing old 16-bit games
