Re: Living without a personal smartphone
Here in Brazil an IPhone is considered an luxury item and a symbol of status. I usually see people talking wonders about it and I think most of them are probably tue, but I simply don't see myself using that many features, since they have similarities with others that I just don't use anyway. Man, I...

Re: Living without a personal smartphone
Well, I mostly use my phone to save some bucks on my energy bill and also test my patience and resilience. lol I really started to use the it when pandemic times arrived. I was kind of forced do buy a newer and better one so I could use video calls and Home banking, things that where very slow and a...

Re: "What's wrong with this Brazilian bootleg Battletoads?" video
That's interesting.
But I think I remember to have seem that Battletoads 2nd stage bug happen on an US NES back in the day.
Maybe it's just some mixed memories of me...

That's interesting.
Would this be possible with Street Fighter Alpha 2?

Re: Help with SNES Jurassic Park save patch
You’ll have a hard time finding a 1mB 5v Fram. Yeah, the 1mb ones I've found uses the SPI bus. The biggest one I've found is 256kb. Not a really bad idea to make a board with 4 ICs, 2 on each side and a demux, but since this one is a one-off and I really can't spend much money on my hobby I'm leavi...

Re: Help with SNES Jurassic Park save patch
You'll have to read the datasheet for the SRAM Ok, I took a look at the datasheet , let's see if I got it right: Captura de tela em 2022-11-05 14-52-25.png It talks about standby mode, not data retention, which should be different. But it looks like I either should pull /CE1 high or CE2 low without...

Re: Help with SNES Jurassic Park save patch
Thanks guys! I've found an Amic LP621024D-70LL SRAM on a board that was going to be discarded. Not sure if it's a good option, stand by power consumption should be aroud 50 ua, but it's what I have for now. Had put it on place of the old chip insulating the upper pair of pins of each row and the CE2...

Re: Help with SNES Jurassic Park save patch
Oh, that's it! Thanks, Memblers!! In the documentation, the author says it needs at least 64k for a single file. Looks like he means 64 Kbytes! :shock: Yeah, I've found an SRAM file on GBATemp that's 128 Kbytes. So I'll need to expand the SRAM instead of shrinking it. I have a few ideas I can try, p...

Re: Help with SNES Jurassic Park save patch
It looks like the author was kind to share his work on DropBox.
Unfortunately, I don't know if it should work with real hardware, nor how to fix it and apply it to the ROM.
Can someone please take a look and see if the code is fine and if there's some hardware problem?

Re: Help with SNES Jurassic Park save patch
At this point, I would look into the code, That's what I was afraid of. Is the FXPAK test made by Ziggy587 any evidence that I may have something wrong with the modification? If so, what could work on the FXPAK and not on the repro? A different memory mapping perharps? Looks like it's time to try s...

Re: Help with SNES Jurassic Park save patch
Well, I think I was vague when I said it isn't saving... I tested playing with the 1st file. After the game over it showed the small percentage I did get. The 3rd file was showing 100%, so I tried it. The game started and I was stuck and soon died and got a game over again. After powering the consol...

Re: Help with SNES Jurassic Park save patch
Damn those viruses that mess up cart hacking! Yeah, but looks like it was trying to steal some sensitive data from me and got triggered by SNES Tool, who knows why... Guess I've found a bug on a virus! :lol: Glad you got it working. :D I was very glad, but discovered just a few moments ago that it ...

Re: Help with SNES Jurassic Park save patch
Oh yeah. That was it! Somehow the PC I was using was not generating the swapped files correctly. I generated in other PC, erased and reprogrammed the EPROMs and voilà! 20221031_200521.jpg After all I just ran an antivirus on that PC. It found some viruses and after the removal it didn't boot anymore...

Re: Help with SNES Jurassic Park save patch
Or if you have a 74LS139 or 74LS00 on hand, try wiring the EPROMs up with that and remove the MAD-1 and SRAM. That way it'll point to a ROM problem or something else. Did that yesterday before going to sleep with the same results. I did a "quick and dirty" test just now: - Asked my wife t...

Re: Help with SNES Jurassic Park save patch
Tried the 74'139 with the same result. :-( load the vector from 00FFC/D So the 1st ROM staying active probably means there's some bad data that makes it crash. Any chances of a failed swapbin? Did it happen to anyone? I'll do a CRC check on the files I programmed vs non-swapped files, I think this m...
