    I already have the Pokemon Games I'd want to use with the Gamecube games and I can just inject the GBA 'mons into the DS games if necessary. I was hoping for an all-in one solution so I don't have to bring so many game cartridges around with me and not pay $100 for an Everdrive just for Gamecube compatibility.

    I'd offer to mod your Gamecube for you just so you could find out for me. But shipping out your console might be too expensive.

    (pokemon question) - Does palpark work with this or older models, without codes/patches for the ds games?

    I know it wasn't possible with the previous model without patches. I'm hoping to find this out as well.

    I don't have any of the Pokemon games to test, so I can't verify any of that. However the RTC works in Boktai. Sorry I can't give more info on tie-in games. EZ-Flash seems to be having some issues with NOR and power draw which they say they're working on. Honestly, though, I have no use for NOR at this point. The 32MB PSRAM has been more than enough for me.

    There is also some talk about working on the direct save to improve the compatibility. I know that previously EZ4 patched games are hit and miss--The Legend of Zelda The Minish Cap with EZ4 patches will say fail to save-- and non-EZ4 patched romhacks--similar with at least a Boktai romhack that I stitched together however Prof 9's works fine RTC and saves. I presume this has to do with the save auto detect, so I'll probably toy with that more to see if manually setting it will work around it. Your best bet, though, is really to just use clean roms where possible unless you're adventurous or someone else verifies they work.

    Copying a game to nor through gba explorer on a ds bricked my reform (well not a full brick but it can’t be used anymore loading roms from sd card only writing to nor from a ds) Should gba explorer be avoided on this card too? It seems to overwrite the cards kernel completely.

    I'd avoid using gba explorer on anything that's not a pure-nor cart. Like you say, you have a high probability of overwriting the card's firmware/kernel/whatever. I am curious, though, if gba explorer could restore the kernel/firmware/whatever if you had a good copy. The real issue is that the kernel on EZ4/EZ form is, AFAIK, not something you're supposed to ever update so no one but EZ-Flash would likely have a copy and it's likely to be keyed to revisions. So, maybe they'd know how to unbrick it?

    No reform here to test with but I thought I would give it a go.
    Test setup
    Original GBA. Cheapo zinc-chloride AA batteries.
    Shoved a bit of paper between one of the terminals and a battery. Attached a wire to each side of the paper and my ammeter between the two.
    For the really curious
    ez_omega_power.JPG

    Game of choice. Minna no soft tetris, mainly as I have an original version here. Same volume, same GBA, my personal rip of that ROM (not that there are any v1.1 or whatever versions) where applicable, just letting blocks drop in the main mode default settings and observing for a little while. The song it plays is a bit random but should not trouble things here.

    Results. All measurements in A as my piece of junk meter is only fused for 200mA and I would rather not replace a fuse today.
    Original game cart.
    0.10, 0.11 at times.
    I did also try my motoGP game. Marginally less at times, other times (menus rather than the game proper which surprised me) a bit higher.

    EZ4 miniSD (my long suffering 512MB miniSD in it)
    spiked to 0.14 when writing to PSRAM
    0.12 in game

    EZ4 microSDHC (closest I have to a reform, same 8 gig class 2 from the Omega tests and used also in omega test below)
    0.13 writing
    0.15 game

    EZ Omega
    Somewhere between 0.22 and 0.20 in the game, second boot and beyond seemed to be less. Clean mode both occasions.
    Omega. The stock firmware it came with, the EZTeam have provided me with later firmwares and are working on the power issues but they are not on my cart yet.
    In menu 0.15, 0.17, 0.18
    There is a problem with the NOR right now but they are working on that.
    Tried boot with addons and there was a massive spike. I managed to lose power at that point (should use more than wires twisted around my fine tip multimeter probes, though it might have also been over current -- my bench supply is out of action so I first tried to power it from a wall wart but all those I had around 3V were pretty wimpy in the current department which saw similar behaviours even on a cart less GBA) and got an error 3 when trying next time. Will have to sort that and try again.

    So yes the Omega does seem to be a bit of a thirsty fish. Leaving it in the menu the draw crept up as well, and had spikes from time to time.
    Double current draw would at least half your play time, possibly more as more current tends to lead to greater voltage drop. Will keep an eye on it as the kernels roll in.

    Unnecessary additional info:

    It's simply an abbreviation for "mervärdesomsättningsskatt" which has kind of become its own word. The same abbreviation is used in Danish (meromsætningsafgift) and Norwegian (merverdiomsetningsavgift) so it's not a uniquely Swedish word.

    Oh dear. I was all aboard the Omega hype train. But double the power draw of an original game? That's a deal breaker for me. Please let us know if any firmware updates make any significant changes. I'm on the lookout for a new GBA flashcard, but the Everdrive is looking good now - it has a similar power draw to an original game.

    WANT! Can't wait for the full review. Try the Shrek 2 movie to see if their odd bank switching is handled, please.

    This is definitely also a deal breaker for me too. I want to use this on a Gameboy Micro which has a tiny battery as it is. This cart on top would kill the battery life very quick.

    I have to wonder if adding the RTC adds extra power draw. How does a standard Pokemon R/S/E cart stand with power draw?

    I would place the power draw at the feet of the FPGA. Many of the older carts tested above used a CPLD, a lesser device as far as programmability but usually better on power consumption.

    Clock chips are nothing terribly power hungry.
    From a datasheet of one it might be on the cart, and if not it is a contemporary device and they are all much of a muchness really
    Screenshot_2018-04-06_02-18-17.

    Mechanical clock mechanisms like hobbyists put in clocks are often quite power draining. You might have heard of that before.
    Back on the chip it is all enough that you probably want a battery rather than a supercap for a flash cart type usage scenario, and if it was like the older devices which used a battery to sort your saves (either fully or just until next boot) then it is even more of a concern but for this I doubt it. Maybe if the battery is being charged all the time then it could affect it but I am not sure they went with such a thing for this one.

    If it is indeed the FGPA then the EZTeam do indeed have a chance to sort it (the thing about them being programmable is you can redo your code/design to maybe use a bit less juice).

    yeah such as implementing an efficient IRQ system that relies on wait for (some hardware) to interrupt, that saves battery time. I can vouch for this

    There are actually some hacks for the GBA to do just that for some games

    @FAST6191 - Have you had any issues with memory card corruption? My test SAVER folder has 167 entries, and I think that's causing times to save to take a good bit longer than the stated 2-3 seconds. With a lot of testing, it seems that if the SAVER folder is near empty, there's virtually no chance of corruption even if you reset pretty quickly.

    Other than the power down during my current draw tests then not so far. I tend not to save and run off for dinner though.

    Saver folder wise I have not plied it with hundreds of ROMs yet but it has a fair few (from the start it had my fairly well loaded, and probably fairly fragmented, one from my EZ4 in it). I could see it being slightly longer, more games certainly changing how things play out before and it being reasonable to imagine it also being a thing here. I will probably have to film my timing tests though as "feel" wise I am still trained from however many years now it is from the EZ3 on up.
