I tried to upload the file via serial, with NOPS, several times but it always gets stuck at about 37%. To be safe I downloaded the file a second time but the result did not change.

Could someone please, with a 8MB mod mind testing my PSX.EXE?
Basically, it's a .cpe program from the SDK which does the MIME animation, converted to a psx.exe with the media appended to it in the correct 8MB memory locations.

Ciao! :D

Another use I found for the extra RAM is to try CTR custom tracks. In conclusion, as far as I know, at the moment only with this game is it possible to use the extra RAM.

Last year I saw that there are some cheats for GT2 that require the Dev Console mode on Duckstation to improve the ...

A couple of months ago, following an indication in an old message of Trimesh, I also tried upgrading the video RAM by piggybacking two SGRAM chips and connecting the CS pin to the corresponding MCS1 pin of the GPU. It is also interesting to note that most motherboards have a convenient pad on which ...

Maybe this is the first time a game use the additional RAM on real hardware?

However, I am satisfied with the result and I would also like to try some mods for GT2.

Ciao!

I think it worked with the executable that szalay_1 sent me and I thank you again. ;)
I don't know if the test times are regular, in my case about 40 seconds pass between the initial screen and the completion screen, but I have launched the test many times and it has always been successful ...

how are you sending via serial?
If you use unirom, just add /m to the commandline to see the console output?


Sorry for the late reply. I use a normal FT232RL USB-Serial adapter installed inside the console for loading .EXE files and as mentioned, both with PSXSERIAL and NOPS everything works ...

It's very likely that the memory is being trashed. Check the address size and offsets. When Trimesh was developing and testing the program it was loaded by another method and not a serial uploader.


Thanks for the reply! :D As I thought there was something wrong, but I preferred to choose the ...

I'll start by saying that I'm probably doing something wrong so please have mercy on me. :? I tried to launch the RAM Test (the MAIN.EXE file in the zip attached to the post in the first page) both with PSXSERIAL with the CD and with NOPS via a cartridge with UNIROM. In both cases with little ...

"didn't have a chance to test them before desoldering them"
Yes same as here, bought from eBay and no other choice just soldering them... and waiting with great excitement to see if it works or not. We're lucky !
It is also very reassuring after a ram test that all 8 megabytes are available!
BTW ...

A very fun project to spend a Sunday afternoon on, with the constant thrill that the RAMs wouldn't work because I didn't have a chance to test them before desoldering them, but luckily it went well on the first try. The console works perfectly but in the next few days I will check the RAM with the ...
