  1. Thanks for the replies -- yes, I was referring to the "Enable 128k Hack" (page 20) feature of the TMS9938... any advice on where I may find more information? Bill
  2. Hi everyone, I'm interesting in using the expanded VDP addressing feature in Classic99 -- I've read the documentation, but am not clear on exactly how to access the VDP Ram using this feature (i.e., register usage, register setup, etc.) Can anyone direct me to further documentation or offer information? Thanks in advance, Bill
  3. I also run Classic99 from Downloads/Classic99 under Windows 10 without any problems.
  4. Thanks for the reply -- my s/w (running on an actual TI-99/4A) swaps in 8k chunks. At this point I think I'll abandon trying to get it to run in an emulated environment as is, and start re-writing to employ a MiniMem cart + 32k memory expansion. A bit more work, but it seems like that is the only option open to me. Thanks again, everyone, for your replies. Best regards, Willie
  5. Thanks for the replies everyone. Yes, I've written some assembly-code programs that take advantage of the SSII RAM configuration and would like to duplicate this functionality so that I can run my S/W via emulation. I was wondering what it would take to create a "module" that would be recognized by an emulator to let me run my S/W.
  6. Hi everyone, I'm new to these forums (joined within the past few months), and I have a SuperSpace II cartridge which I purchased decades ago and would like to create an image usable by a TI-99/4a emulator. Can anyone direct me to a tutorial on how to do this? My SSII cart is getting up there in age and I don't know how much longer it will continue to function. Thanks in advance, Willie
  7. Hello everyone, I've just downloaded the latest version of Classic99 and I'm getting a (generic, I believe) warning from Windows Defender. I think that that last version of Classic99 that I have running on my Windows 10 laptop is two version old, and it didn't spawn this warning. I assume that everything is fine with the download, and am hoping this has something to do with the last series of updates from MicroSoft. Has anyone else encountered this issue? Thanks in advance, Willie
  8. Thanks for the replies everyone. I'll follow-up on your recommendations. I appreciate the help! Regards, Willie
  9. Hello everyone! I'm new to the forum, but have been programming my Ti-99/4a since the mid-80's. Recently I moved to a Windows-10 based laptop, and find NotePad / WordPad a bit frustrating to use when writing assembly programs -- in particular, managing the tabs! Can anyone recommend a replacement for these? I'm curious as to what others are using. Thanks in advance, Willie
  10. New to the forum -- reading the Lurker's Guide to the Galaxy as I type :-)
