| Game update | Hotfix 1.3.3 More fixes! · 74HC245 fixed issue with the DIR pin not functioning correctly and causing a crash due to matrix error · Corrected pin labels for 74HC245 and 74HC273 · Fix issue with a single remaining pin label after a component delete with pin hints enabled All the best Mike | — | |
| Game update | Hotfix 1.3.2 I have removed support for AVX2 for the time being as it would appear that some users do not have support from their CPUs. The performance loss is negligible, if any, and should stop crashing for affected users! As always, please get in touch with any issues that you may be having All the best Mike | 16579500 | |
| Game update | Hotfix 1.3.1 In the last 24 hours since 1.3 was released, a couple of errors have been noted. I have worked hard with several users to isolate the problems. I honestly cannot thank them enough for their patience. I have updated a few key areas, which should significantly improve stability and hopefully stop some users getting crashes when placing unconnected components and creating wire loops with switches.… | 16572311 | |
| Major update | v1.3 is now available Better late than never... Simulation speed was always the limiting factor for the future of CRUMB. No matter how much work I put into other areas, I was always hit with the same issue and I was not able to achieve the vision that I wanted for CRUMB. Initially I had said that I had found a 2000% increase in performance with last month's development update, but that milestone has since been blown… | — | |
| Game update | Quick progress update Hello everyone, just a quick update on progress! I am for the most part complete with the speed update, it is actually now possible to run some of the circuits at 96,000Hz which is great news... especially if you want to create circuits for audio/analog processing 😍 However, I am going through a few checks and tidy ups with everything to do with audio input as I want to compile two updates in… | — | |
| Game update | Hard at work on CRUMB 2.0 Hey everyone! Long time since the last update, but I have still been working away hard between my real job and young family! I have been gathering lots of info from all the users and my whiteboard is now covered in ideas and feature requests I am not quite ready to show new screenshots/video recordings as the latest User Interface is very much in a debug/alpha phase and does not represent what… | — | |
| Major update | Update is here and now available on MacOS Finally the Update is here! Thank you to everyone who has been patient whilst I have been working long days and nights to re-write the vast majority of the Core UI code. CRUMB may not look too different, but underneath what you can see, it is now a very different and streamlined program. There should not be any issues with numerical entry or crashes. However should you find any other problems d… | — | |
| Game update | PLEASE READ: Workaround for crashes and issues Quite a few users, especially those whose number systems use a different format to GB English, have been suffering breaking crashes and it has forced me to rebuild the user interface from scratch... however, a kind user on the CRUMB forum has tested a workaround for now that may be of use to some of you with problems. CRUMB Forum post Basically as a temporary measure, if you would like to use t… | — |
