    Hello, All!

     
    I've published the free ColEm 5.4 for Windows and Linux, a new version of my ColecoVision and Coleco Adam emulator. There is also source code for those interested in porting ColEm to other platforms:
     
        http://fms.komkon.org/ColEm/ -- homepage
        http://fms.komkon.org/ColEm/ColEm54-Source.zip -- portable source code
     
    This release adds a simple CPU-based linear interpolation scaler, used when GPU-based scaling is unfeasible. The Windows version now supports drag'n'drop for files. See below for all the changes.
     
    ALL CHANGES:
    * Added simple CPU-based linear interpolation scaler.
    * Added file drag'n'drop support to ColEm-Windows.
    * Added "-linear" command line option to ColEm-Linux.

    Hello, All!

     
    I have published VGBAnext 6.4.1, a new version of my universal GBA, GBC, GB, and NES emulator for Android:
     
     
    The new version fixes melodic sound operation with DirectSound disabled. Thus, games like International Karate and Phantasy Star should have sound now. As you remember, I had to disable cheat features to avoid Google staff banning VGBAnext from the store. You can easily reenable cheats by downloading this file to your "Downloads" folder:
     
    See below for the complete list of changes in this release.
     
    ALL CHANGES:

    * Fixed melodic audio playback when DirectSound is off.
    * Fixed sound in International Karate.
    * Fixed sound in Phantasy Star.
     

    Have fun!

    Hello, All!


    I've published the free iNES 5.9, a new version of my NES and Famicom emulator for Android:
     
    https://play.google.com/store/apps/details?id=com.fms.ines.free -- on Google Play
     
    I am releasing this version as both standalone APK and Google Play download, since I am not sure if Google will allow me to continue keeping it in Google Play. This release is based on iNES 5.9 for Windows and Linux, published this week. It adds a simple CPU-based linear interpolation scaler, used when GPU usage is unfeasible. There is also a separate "Video | Interpolation Effect | Linear Interpolation" option now. See below for all the changes.

    ALL CHANGES:
    * Based on the latest iNES 5.9 sources.
    * Refactored scaling and special effects framework.
    * Added simple CPU-based linear interpolation algorithm.
    * Added separate option for linear image interpolation.

    One nice side effect of using the frequencies is that (at least to me) the result sounds much nicer/"upscaled" to taking the more hardware faithful approach. Downside is lower compatibility (AY was also used on Vectrex, which had a bunch of original era games that made use of sampled sounds).

     

    The DAC trick mentioned above is pretty much the only incompatibility, as far as AY891x is concerned. YM2608/YM2612 and other FM chips really require a sample-based approach.

    FYI, the AY code from MAME supports it... You could check that out.

    I have a policy of writing my own code. Having said that, it is more or less clear what is going on. The software stalls a PSG sound channel, then manipulates its volume in real-time, as if it were a DAC of sorts.

     

    Since PSG emulation in ColEm works in terms of frequencies/volumes, rather than audio samples (letting you record PSG music into MIDI), simulating this pseudo "DAC" behavior is very messy. I do have it on the todo list, but the two or three games using this "feature" make it a low priority.

    Curious, and I didn't see this in the thread anywhere (although I may have over looked it).  But I am not getting voice from Wizard Of Wor for the android version.  Is there known issues with that game not working with speech with the emulator or am I missing a function within the options (I have the SGM checked).  Thank you!

    I think the problem there is that the voice is done via some PSG hack, since AY891x PSG does not provide sampled output capabilities. Such hacks are not emulated by ColEm at the moment.

    Hello, All!
     
    I have released ColEm 5.2 for Android, a new version of my Coleco emulator:
     
     
    This release is based on the latest Windows/Linux version released this week. It adds built-in menu options for selecting hardware model, working with disks and tapes, and saving printer and MIDI outputs. I have also improved the Box Art Downloader, making it follow URL redirects and store downloaded box art at alternative location, if the original ROM file is located in a protected folder. As you remember, I had to disable cheat features to avoid Google staff banning ColEm from the store. You can easily reenable cheats though by downloading this file to your Downloads folder: 
     
    ALL CHANGES:
    * ColEm Deluxe is on $2.99 sale at Google Play this week.
    * Based on the latest ColEm 5.2 sources.
    * When parent folder not available, showing storage devices instead.
    * Made multiple fixes to Box Art Downloader.
    * Fixed Box Art Downloader to use alternative storage location.
    * Fixed Box Art Downloader to follow redirects.
    * Added HTTPS support to Box Art Downloader.
    * Reorganized built-in configuration menu.
    * Added built-in menu options for saving printer and MIDI outputs.
    * Added built-in menu for hardware model and options.
    * Added built-in menu for Adam disks and tapes.
    * Fixed built-in menu palette selection.
    * The LoadFile() function will now try loading .STA files.

    This release reorganizes the built-in menu (F5 or CTRL+F5 in Adam mode), adding new options for hardware configuration, disk, and tape drives. The Windows version fixes window resizing and positioning, and adds saving last selected physical gamepad. Finally, the Windows version includes the new "File | Clear Settings and Quit" menu option for resetting entire configuration. See below for all the changes.

    Is there any way to reset ColEm to the default settings that are there when you first install it? I screwed up the video somehow and I can't figure out how to get it back to the way it was originally.

    Just letting you know that the latest ColEm 5.2, released today, includes the "File | Clear Settings & Quit" menu option.

    Any chance of a GP2x port?  The existing CV emulators won't work with a lot of the new ROMs and has no SGM support because the last version released was before all this stuff.  The GP2X is a handheld Linux gaming system, the follow up to the GP32 and the predecessor of The Wiz.  I still use mine quite a bit and it would be nice to have a better emulator.

    Well, the ColEm source code is available from the web site (with some minor legal caveats), so you are welcome to do a port.

    On Android, there is a "Settings | General | Clear All Settings" option. On Windows, RegEdit is probably your only choice right now, but I am adding a similar option in the next release.
