Have to admit at first when I transfered the files from 1.1 I wasn't too impressed with this version(especially what it did with the files). But starting fresh, I have to say I love it, and much more easier to use.

Can version 1 be used with TSU9800 having real difficulties with transparent buttons in the latest version

No, it cannot. Forgive me if I mistake you for someone else who recently was reporting issues with Contest Entry #8.

Edit the images in Contest Entry #8 or contact the author to get an updated file.

I'm close to purchasing a TSU9800 myself and will not be using PEP 2 for anything other than a download tool. I'll be doing all my work in PEP v1.1.20 for both my TSU9600 and TSU9800, then opening the file temporarily in PEP 2 when needing to either download to the TSU9800 or test ProntoScript via the Simulator.

That being said, there is one thing one needs to account for programming wise per the TSU9800 over the TSU9600. The TSU9800 has two additional hard buttons, "Info" and "Back". These hard buttons can easily be programmed for outside of PEP 2 however, thanks to PEP v1.2.60 for the TSU9400 as the TSU9400 also offers these hard buttons. That programming is then retained once reopening and saving the file back in PEP v1.1.20 for the TSU9600 even though the GUI doesn't provide access to those hard buttons. This allows you to then simply open the file in PEP 2 for download to the TSU9800. In fact, what I plan to do per my XCF is add ProntoScript functions for the "Info" and "Back" hard buttons via the TSU9400 editor. Once saving the file, then reopening and saving the file back in the TSU9600 editor I'll be set to go. I won't ever need to go back to the TSU9400 editor per programming these hard buttons. If at any given point I want to change what the "Info" and "Back" hard buttons are assigned to do I'll simply update the function I've assigned to each at the activity level for a given device. So in a word, you can have your cake and eat it too. Your "cake" being PEP 1, and the "eating it to" being the ability to then download your XCF to the TSU9800 per PEP 2 without having to do any actual programming in PEP 2.

Wow! 10 years of PEP2. I still used it in lieu of PEP3.

Platform still going strong, even without a new firmware release.

Same here. I never bothered going from PEP2 to PEP3. So many years later, and I still haven't found a better universal remote than the Pronto.

Wasn't Phillips making any money? I still think they should reinstate this part of their business. The only good thing is that you can get used remotes for peanuts

Agreed. Must have been too few willing or able to pay for a top-shelf remote to support the business case for the Pronto Pro line. They were the best programmable IR remotes ever made, but were way too pricey for most folks, including me, when new.

But I'm now using a like-new 9600 that I picked up for a few hundred USD, and love it so much that I picked up a second 9600, just in case the one in use ever cashes in its chips.

I'm also still using my tired, laggy and worn 9600 as just nothing out there that comes anywhere near the versatility of Pronto remotes but now beginning to have issues. Uploading is sketchy and on W7 keep losing connection so thought I'd try on an old XP laptop. All was good running pep1 and opening my config file to edit but for one thing, if I had text added to buttons or even attempted to add text the software refused to display the text, I'm stumped now and sadly thinking has all this had it's day and with breaking heart is it time after over 20 years dabbling with Pronto's time to say goodbye 😭
Update:
Followed advice from Lyndel and reinstalled using my old XP laptop and all is working great again, how can I ever part with my Pronto and this great site.

I use both PEP1 and PEP2 on Windows 7 32 bit.

Maybe the 32 bit is the key. :-)

Here is the solution for issue for the post immediately prior to this one.

No problem here with Win 7 64 bit.

For PEP1 or PEP2?

PEP1

I run Pep 2.4.23.0 on windows 10 with no issues. Handles 9400,9600,9800. I am looking for a 9800 as I spilled some soup on my 9800. It is sitting in flower desiccant, hopefully it will dry out. I don't use info or back so I might be Okay using my spare 9600 until I locate a reasonably priced 9800. Saw some on eBay for $385 +$50 shipping so maybe 435 gets me a spare.
