A third SXROM game ? Cool, I always tought there were only 2.

Does it use all 32k of SRAM ?
As far I know both Final Fantasy I & II and Best Play Pro Yakyuu Special used only 16k (both are multicard with 2 games on them I think, please tell me if I'm wrong).

デザエモンはゲームを作るソフトだ。自分はこのソフトを使ったことがないが、ユーザーに聞いたことがある。
このソフトでは4つのステージを作ることができる。4つのステージのデータは RAM の page 0,1,2,3 が Stage 1,2,3,4 になるというので、おそらくSRAM全てを使用している可能性が高い。

このユーザーは絵描衛門がエミュレータで正常に動かないと言っている。

ちなみに、絵描衛門はエミュレーターでは正常に作動しません。

エディットモードで保存する事が出来ず、フリーズしてしまいます。

So basically as far as I can understand you, this game uses all 4 SRAM banks to allow the user to edit 4 different stages ? Sounds rather unique for a NES/FC game !

It seems current emus would emulate SNROM instead (with no SRAM banking) and crash on edit mode, as the emu refuses to switch RAM banks ?

I also see that the PRG-ROM is 28-pin so it means its size is 128kb or less, so they definitely used this board for SRAM banking solely.

Naruko is asking how to register and submit to bootgod. I have never done that so I don't really know.

As far as I can remember you have to talk to Bootgod directly, there is no automatic process for registering. Send him a PM.

@naruko: I've documented the 32k SRAM in MESS. thanks a lot!
I'm not fully sure how to verify that the saving/loading on different banks work (I hate dezaemon editor :) ), but FF1+2 works fine in MESS so I would expect this to work too...
