Re: Compiling X-Flash

Changes now on github, thanks for the PM Squaresoft... What's new in X-Flash v1.2 - Beta 7 ----------------------------------- - Added *untested* support for AMD 29F010 128k Flash (Manufacturer ID=0x10, DeviceID=0x20) - Renamed Sanyo.. to GENERIC 128k as this Man/Dev ID pair seem to be used on vario...

Re: Compiling X-Flash

Yes they can, but I wouldnt try modding the powerplay iii, youd need to replace it with another PLCC, and they are so fragile its not worth the risk.. the other carts just disable the onboard chip and solder in a DIP32 socket and off you go. As for what to recommend... I dont know what advantages a ...

Re: Compiling X-Flash

Hi Squaresoft, I have added AMD to the code, but I do not have any of those parts to test it - so use at your own risk. I have checked the datasheet and the flash protocol looks pretty much standard from the addressing and unlock code perspective, so it *should* work, but use at your own risk! Xflas...

Re: Compiling X-Flash

That would be great, then we can hopefully get the flash support more complete. On the name, I kind of wanted to lose "flash" from the name, as my idea is to make it more of a toolbox. The working title for my Wifi client is pstool, so might just name it the same. This is more to further my own lear...

Fonts

Does anyone have an example of how to use different fonts in your PsyQ projects?

I wanted to look at using other fonts but all the examples I can find just use the built in stuff.

Thanks

Re: Compiling X-Flash

Hi Squaresoft, thanks for the info.. The two cartridges that are detected as D0 01 should be supported in the last version on GitHub, as its the same ID's as the clone Sanyo I have already added in(see on Github) - so I would say its a counterfeit Intel flash part. Assume CSI is just some generic br...

Re: Compiling X-Flash

Bit more research.. Looks like the 28SF040 uses the same software chip protection and commands as the 39Sxxx series.. The lock/unlock command sequence seems the same so will hit the sources this evening and see what I can fathom. Might be a simple case of detecting the chip and making it use the dif...

Re: n00bDEMO - Demo made using my own SDK

This is an absolutely impressive work you made here, and I am expecting to see how far you can bring it. I really want this project to grow and become the new standard for PSX programming, so we all finally have a robust open-source SDK built by enthusiasts to enthusiasts and forget about closed-so...

Re: Compiling X-Flash

Now I understand, sorry for the misunderstanding. That makes sense now, that will be down to the fact that the cart is constantly in use as its a replacement for the on board BIOS. I used to find a similar issue with my cart that I use for development.. if you remove a EEPROM/Cart whilst the PlaySta...

Re: Compiling X-Flash

Thanks for the feedback. Interesting regarding the hotswap.. which version of xflash were you using when the hotswap worked okay? Also, when you say hotswap are you hot swapping the ROM or the whole cartridge? I haven't actually changed any of the core code, just added some flash part in and an extr...

Re: Compiling X-Flash

No worries, I will leave it be.

If you get any carts that show "UNKNOWN FLASH", can you let me know the ID numbers it reports and what model flash it is? I can look to getting extra carts added (would be a great help).

Re: Compiling X-Flash

So with the 39SF chips I seem to remember it using more address lines for write commands then the older chips. I found a thread on nesdev where it was discussed a little. https://forums.nesdev.com/viewtopic.php?f=9&t=16029 Not sure that is helpful. Thanks for this, very helpful indeed.. helps under...

Re: Compiling X-Flash

Hi, Thanks for the info, will double check the datasheet and have a read. Very helpful Update: Just got a clone AR cart that wasnt detected in Xflash - It has a Sanyo branded LE28C1001T. Interestingly Sanyo branded flash parts are just SST.. so usually use the SST Manufacturer/Part ID's.. this one d...

Re: Backup of Gamars Internal VCD Card

I doubt if it would work on a standard AR cart, think the internal/external bit isnt the issue but the rest of the missing hardware perhaps..

The VCD card doesnt use a simple PAL on this one, it has a Lattice CPLD.. so that might be doing some magic that the menu expects?

Re: Compiling X-Flash

As promised, find attached the attempt to flash the 39SF020.. Writes something every 100h bytes.. so its trying at least. Have also added the source and compiled EXE.. I have added the definitions in for SST39SF020(256k) and the AMD Am29F040 (512k). Literally emptied the garage looking for 28/29 ser...

Re: Compiling X-Flash

Had a look after the failed write,, seems that it writes one byte per 100h bytes... Ill post the files for comparison later. Tried with different page sizes and that didnt work.

Re: Compiling X-Flash

Looks like it might be worth looking at the SST 28SF040, as it supports byte write and sector erase (possibly similar to the flash operation of the 39F020. Investigation continues :-) Will work on pushing this to github tonight. Will keep the versioning the same but this can become v1.2 b6 as it has...

Thanks Shadow. I am working on getting something working in ROM still (hence all my other posts), but one thing I would really like to get working is binary file upload (helpful for Yaroze).

Ahaaa,, amazing what you find when you read things correctly... So in the datasheet for the 29EE020 :- • Fast Page-Write Operation – 128 Bytes per Page, 2048 Pages – Page-Write Cycle: 5 ms (typical) – Complete Memory Rewrite: 10 sec (typical) – Effective Byte-Write Cycle Time: 39 µs (typical) So 262...

Re: Compiling X-Flash

Think we do need to update it, completely open of course. Had a further play with this. Modded an old EMS AR clone and added a ZIF slot to make life easier. Then tried a SST39SF020A in a PLCC32 adapter. Pre-flashed it with Caetla 0.38 and loaded my modified code into the memory card. The flasher wor...
