Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2442.mcz

==================== Summary ====================

Name: VMMaker.oscog-eem.2442
Author: eem
Time: 19 September 2018, 9:22:37.266528 am
UUID: f7e49724-6cf7-484b-a024-25d028888354
Ancestors: VMMaker.oscog-eem.2441

Final piece of Pharo compatibility to allow e.g. the REPL startreader images to run in Pharo 6.1.  Split the input dialog for FakeStdinStream so it works both on Pharo and Squeak.
