Sent from my Pixel 6 Pro using Tapatalk I have a old sansdisk 128mb micro sd in a micro-to-sd adapter. This card has been a real champ, had it over 10 years. I originally got it to use with my Nintendo DS flash cart, but i hardly use that anymore so i started using it for my Finalgrom. I have a really ancient 32mb MMC card laying around too, from back in the Nokia NGage days. Will Finalgrom read a MMC?

Nightengale Posted January 1, 2022 Share Posted January 1, 2022 Well, I put the cheapy SD card in and no change. Then I checked the cartridge port, wow, that felt was groaty! Cleaned that up, thinking, well this is it, it will work; alas no changes. Hmmm I guess it's time to get the fluke out...I don't have an o'scope, logic probe or spec an.

+dhe Posted January 1, 2022 Share Posted January 1, 2022 Do you have a different console to try? If you want to PM and send me your SD card, I can try it in my FinalGrom... Quote Link to comment Share on other sites More sharing options...
Nightengale Posted January 3, 2022 Share Posted January 3, 2022 Thanks much dhe! I have another console to try it on. Curious issue Quote Link to comment Share on other sites More sharing options...
Nightengale Posted January 4, 2022 Share Posted January 4, 2022 A different console and it worked, but no F18A, I'll need to continue to narrow this issue down on the original console. Quote Link to comment Share on other sites More sharing options...
+dhe Posted January 9, 2022 Share Posted January 9, 2022 For normal operation, does it matter if the write protect tab is enabled or disabled on the sd card? I ask, because one of my cards has no positive click, and I believe inserting and extracting changes the position of the switch. Quote Link to comment Share on other sites More sharing options...

Asmusr Posted September 21, 2022 Share Posted September 21, 2022 On 5/10/2021 at 3:12 PM, Asmusr said: I often have to go through several rounds of pressing the reset switches, turning the computer off and on, removing the cartridge and reinserting it, removing the SD card and reinserting it, and whatever else I can think of, before I can get my FinalGROM to load anything. I think it's worse on my F18A console than on my other console, and I believe other carts work fine, but I haven't done any systematic testing. Every time it fails I get a new result. Sometimes it fails on the opening screen, sometimes there is no menu, sometimes it seems to work but then loaded program fails - it seems completely random. In then end it suddenly works, and then I can often load other programs if I just press reset. Replying to my own post since I might have found a solution. My consoles still had the felt pads in the cartridge connector, and yesterday I finally took the time to remove them, and I haven't had any problems since. It's too early to say if that was the problem, but its looking good. For information about removing the felt pads see https://www.arcadeshopper.com/wp/ti-99-4a-faq-maintenance-cleaning-cartridge-port/ 6 1 Quote Link to comment Share on other sites More sharing options...
+9640News Posted November 16, 2022 Share Posted November 16, 2022 A question was asked here about whether there is another terminal program other than TE2 that is available as a cartridge image for the FinalGrom 99? Can someone create a cartridge for something like FastTerm or MXT and make it available? 2 Quote Link to comment Share on other sites More sharing options...

tmop69 Posted March 25 Share Posted March 25 In December I've purchased a second FinalGROM and it seemed to working fine, although I've just run some quick tests with some of my preferred games (Donkey Kong, Munch Man, etc.). Today I used it to test one new homebrew I'm developing and it was crashing. To summarize, after various tests (different TI99, SD, etc.) it seems that the problem is related to the FinalGROM. In particular, it's not able to run the varios XB, RXB carts, Popeye, the various homebrew/game requiring the 32K. It works instead with QBert, Frogger and Tuthankham from Parker Bros, Miner, the various Atarisoft game, some homebrews (Borzork, Obstacle Course), EA, MM, DiskManager. I've updated it using the last .AVR and .PLD files and also tested with the QI version, but nothing is changed. Any suggestion/advice on other things to try and/or the cause of the problem?

Unfortunately that's not a very conclusive result. addrtest also uses bank switching, so it's not that this is the one cause of the problems. ramtest failing is not that big a deal, and might be a consequence of using the QI firmware IIRC. The difference between addrtest and banktest might explain why some games work and other don't, as banktest uses high-frequency bank switching. This seems like the CPLD has some issues, but it could also be timing issues caused by other hardware. I still have a few CPLDs left, so I could send you one, but this really is hit or miss.

Thanks for the offert, I've agreed with the vendor that he'll send me another FG99 from the next batch. For curiosity I'll run ramtest switching back to the standard firmware to see if I get the same errors. Quote Link to comment Share on other sites More sharing options...
YannAros Posted April 6 Share Posted April 6 (edited) Hi, I just got a second hand FinalGROM and it was working ok for 1 hour. After that is started to behave strangely with some screen corruption and after 2/3 resets I doesn't work at all anymore. As soon as I start the computer I get this kind of screen, the LED isn't flashing (one flash and then stays OFF) I've tested with a blank SD Card and get the same. Did I break something? Shall I try to update it the AVR? Edited April 6 by YannAros Quote Link to comment Share on other sites More sharing options...
Willsy Posted April 6 Share Posted April 6 Maybe try cleaning your cartridge port, and also clean the fingers on the FinalGrom too. Use isopropyl alcohol if you can. If you don't have any to hand use some aftershave! It'll smell nice too! 4 Quote Link to comment Share on other sites More sharing options...
YannAros Posted April 6 Share Posted April 6 I'm answering myself, the issue was with my power supply, apparently it was not powerfull enough to power the TI and the FinalGROM. I've changed to use an original one and now it is working again. 8 Quote Link to comment Share on other sites More sharing options...
