Dont be so negative about this innovative design. It is not at all destroying but enhancing!

The result is a still operational cartridge with added (much!) functionality!

And the result looks good: http://soft.mundivia.es/mpazos/flashrom/MegaFlashROM.jpg

It is very similar to MEGASCSI, also a high quality idea based on the same principle.

I am _very_ postitive about this flash project. But I think there are better ways to get casings & SCC(+).

Laurens, I believe that mentioning Padial as manuel pazos is not strange at all.
I believe there are now two similar products , or Padial has given his permission to Manuel Pazos to sell and changing the chip used. Very doubtfull if you Padial a little
Reason:"Padial uses the chip of lattice 'Mach' and Mnauel uses the 29f040 (that chip is also on our ide). Since our Ide doesnot need all the space programmed, it might be possible to put also some extra software in it. E.g. Powerbasic (that was, laurens what you were referring to in the subject GFX9000_.
But If you want to to this right as Manuel Pazos really want a good product I agree with 'SNOUT' in all his comments. And a CPLD and not aFGA is a solution that is better way. More expensive is perhaps also not true, but that depends really on het 'gates'
you need (no , that one with the glasses)
I put the subject on the agenda for Madrid and will see if they are interested to put it intoÓur SUNRISE BOX.
Last remark to Hans, I donot think this is the PCB used for the new product but simply a changed cartridge.So what I mean I would like to see the real product first

It's destroying the face and internals of a Konami (or any other original MegaROM) cartridge! I would say that's obvious...

Furthermore, this is not an innovative design, anybody can just replace a ROM with a FlashROM, no further design needed!

I don't see how it compares to MegaSCSI at all, maybe you can explain that a bit in detail?

Also, I really don't like being negative (see msg on other thread) and I'm sure effort and good intentions have gone into this project, but I just can't help finding it extremely wasteful to cannibalize on these innocent megarom games!

MegaSCSI is a 'destroyed' and 'cannabilized' megarom with added flashrom and a scsi controller and a different sticker on the outside!
That is indeed a wasteful way of getting a mapper.

The idea of using megaroms is from ESE Factory (Kazuhiro Tsujikawa is mentioned here!)

ThisSCC Flash is equivalent to adding a switch to a SCC cartridge, that also could mean damage to the sticker (and they try to keep the original sticker on the outside if you ask them).

I didn't know MegaSCSI used mapperchips from MegaROMs... But it uses SRAM (not FlashROM) and, most importantly, uses its own PCB. If the mapperchip is replaced by a PLD/FPGA implementation there is no cannabilization anymore.

ThisSCC Flash is equivalent to adding a switch to a SCC cartridge, that also could mean damage to the sticker (and they try to keep the original sticker on the outside if you ask them).

Heh, I'm against modifying SCC's with switches too, I use a slotexpander or extender with a switch Smile

It's not like there aren't alternatives available, namely Padial's FLASH-G and MegaSCC. (Although the availability of the latter is unknown to me)

A small comment. I mentioned the ESE-SCC before, however from a little research I discovered that it is definately not an FPGA custom SCC design, but instead the principles behind it are very similar to Manuel Pazos' idea (hence why he mentioned Tsujikawa, I bet, isn't he from ESE?). The difference is that ESE used an SRAM while Pazos uses a FlashROM.

I wonder if anyone ever took the effort of fabricating a custom SCC in FPGA. There isn't one in the FLASH-G or the MegaSCC already, is there? It can't be *that* hard, considering it's only a simple 5-channel mixer which mixes 32-byte looping samples... In software I could implement it in a whim.

About putting switches in SCC cartridges, ok I guess this is not a very nice thing to do to a cartridge aswell, but at least as much of the 'originality' is preserved and I consider it somewhat of a 'nessecary evil'. Not to be done too often Smile. My King's Valley II cart has a switch, and my F1 Spirit cart I bought later on hasn't got a ROM. So as far as SCC's are concerned, I'm set, and I will definately not touch my newly acquired Quarth (in perfect condition) with a single finger. Well... not literally spoken ofcourse...

And now that I come to think about it, I could understand that some people would rather choose an invisible internal solution to that than an external one which requires cutting in the casing and all. Question is, with the MegaFlashSCC, can you keep a key pressed during boot time which disables the FlashROM, or does it need an external switch aswell?

Anyways, ok, I guess this is indeed a more viable use of an SCC game than using it for MegaSCSI (although that one doesn't particularly need an SCC game, you can use any konami game instead). And as long as you don't to it to too many cartridges, definately not the really rare ones like Quarth and Contra, or whoa, even Solid Snake (argh, that would be a worst nightmare)...

Ok if I understood the thread correctly...

- Sunrise has already got cartridge boxes (which are cool) that could be used
- It is possible to emulate the SCC without using a real one already

so... why would we destroy rare, original ROM cartridges? Just because we did that in the past as well? Hmm.

I'm not so sure about the second thing... I don't know if an FPGA version of the SCC exists already.

AFAIK the MegaSCC from Ademir Carchano is indeed an FPGA implementation.
