The FinalGROM 99

Recommended Posts

I have a non-QI, non V2.2, beige console + speech + nanoPEB v1. If I don't have the SDHC card in, I get the same behavior. A flashing light, and no option on the menu other than TI BASIC. If I put the SDHC card in, then the light flashes once when the TI is turned on and then the FINALGROM 99 shows up on the menu.

 

The SD card I'm using in my FG99 is 16 GB in size from Verbatim and cost about $10 (it was the cheapest/smallest one they sold at the store.)

Just offering it up as a known SDHC card that works in the FG99, should you choose to try a different card.

Thank you Sinphaltimus, Casey, Arcadeshopper - I guess media is what it is narrowed down to ...

 

Rather than get one brand for this card, one for that card (and having to remember which goes with which), could I save up a little more and spend on the Toshiba FlashAir mentioned above? https://www.amazon.com/gp/product/B00UOYPZNE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Anybody have good experience with that brand and does it work with both FR99 and FG99?

Yes, the FinalGROM 99 currently doesn't work on QI consoles, but it should work on non-QI v2.2 consoles. Casey's behavior is the correct one.

 

I do have a QI console right here, and it's showing no menu at all. I just haven't got around to figuring out what may cause this.

 

But in about one week I have a free day, which is slated for the FinalGROM 99.

I had issues using the FG99 with the "QI" board. I believe it is a couple of pages back. IIRC, Ralph plans to work on the issue.

EDIT: Yup, his answer is on the page after your post about your "QI" woes. :)

Some guys were able to get it to work, I think mine was defective and I'm no longer in possession it. Some of the guys have also complained about of having to hit the reset button on it too. To me it was a time consuming hassle. Just my biased opinion here, but you might be better off buying an el-cheapo no-name class 4 SD card and using the sneakernet method for transfer.

 

Great idea, but...

Finally I was able to look at the QI problem. The symptom is that the FINALGROM menu item is missing, although the menu is loaded from the SD card.

 

I used my logic analyzer to see what is going on. I could see right away that the signals seem alright, meaning the GROM emulation is working fine on the QI.

 

Next, I captured all data bytes on the bus whenever GR goes high, i.e., when the GROM data is valid. It would be even better if I could capture GROM addresses, but they generally don't appear on the bus.

 

To get meaning out of my capture, I disassembled the TI 99/QI GROM 0 from MESS, hoping that this would match the GROM 0 of my QI machine. After some searching, I could match the menu generation segment

2.0232,0x0000

.

This byte sequence >d6 >8f >dd is nowhere to be found in the QI GROM.
So, how reasonable is it that my MAME QI GROM 0 matches the GROM 0 in my QI machine? Are there any other interpretations on what is happening?
Up to this point, the FinalGROM is running flawlessly, so I'm still in the dark why the menu is missing.

I've just released bug fix version 1.3 on the homepage, which fixes a bug where programs of images that also have subprograms are not displayed in the FinalGROM 99 menu. One such program is TE II.

 

Again, please refer to the homepage on how to apply updates to your FinalGROM!

 

EDIT: typo

Thanks, Ralph! Any luck on the "QI" console problem?

 

I must admit that I haven't completed my analysis yet. Me saying "byte sequence nowhere to be found" is total bullshit; it just so happens that my QI console is still the original version.

 

I'll get there eventually, but right now I spend all my time on my new project (still secret). :)

Hello,

 

I just purchase a FinalGrom99, and i have some problems:

 

When i put a folder whith some programs inside the sd card i have no menu and the led blink like this : oooo______oooo_____oooo_____oooo

 

but if i put programs in the root of the sd card, i have the menu with the list of all it's content.

 

my finalGrom was in 1.2 version, so i update it to 1.3 and there is the same problem, and 1.1 version too.

 

my sd card is sandisk sdhc 16Gb, i try an old sd card 256 Mo but always the same problem.

 

what can i do ?

 

Excuse my english, i use google translate :(

At the splash screen of the TI99 press the fr99 reset Button on the card it should stop to blink and you should have the right menu. Have you tried already?

@ti99iuc

 

Yes, i pressed the reset button several times, but nothing happened.

 

@fabrice montupet

 

Yes, my sd card is formated using FAT32.

 

I will try with another SD card.

i try sd card 8go class 6, sd card 4go class 4, sd card 256 mo, and no one work

no menu when i use folders, only the led blink like this : oooo-----oooo-----oooo-----oooo, four times, nothing, four times, nothing, continuously.

 

pressing the reset key has no effect.

 

But when i put the progams into the root of the sd card it work perfectly.

 

 

[Edit] SOLVED

 

To display all the folders, I have to put a single program at the root of the sd card

in addition to all the folders, so it works.

 

Thanks for your help.

This is slightly unusual. Four blips imply that you're (auto-)loading an empty image -- which can only happen if you have an image-like file in the root that is invalid or empty. Is there something besides the folders (before you added the image)?

 

Before I send out carts, I always test them with test C, using the "standard" ZIP file from WHTech. That ZIP has only folders at the root, and no files, which means it was working for me and should work for you. :???:

Hi! I just got a FinalGROM from arcadeshopper (Thanks for the great service!) with a pre-loaded SD card. I'm getting no other choices besides Basic. The first two tries , nothing. The third time I started the system, it showed the folders, but when I hit the key, the screen went to a cyan background with 3 black dashes on the right side. I checked the SD card after several more failed attempts and it is readable on my pc. I have a biege console with copyright 1981. I cleaned the contacts and I have no problems with other cartridges. Is this the same QI issue as above?

Do you have a 32K memory expansion?

It's possible to get a cyan screen if you are trying to load a file which exceeds memory.

Try the file included below and see if it works.

I wish I could get to the point to try to load a file. I don't have the 32k, but i was able to read the txt file on the sd card so i can tell which ones need it in the future. Thanks for the tip!

 

 

Is the light blinking on the Finalgrom99? Also have you removed the felt pad in your cart port?

Yes the light blinks. Not constantly, only when I press the FG reset. When I press the TI reset, the unit resets as I guess it should, but no joy on seeing other options on the start menu. Felt?

Hey, is that PeteE's game submission? I am looking forward to trying it on my system real soon!
