I am having problems flashing to some third party carts - others from the same supplier work okay, but these may be different types

I am getting the error as above "Check flash cartridge error" with flash ID EC 2F 80 80

クライアントは、チップ ID を使用してフラッシュカートリッジを識別します。
チップ ID が不明な場合 (クライアントによって認識されない場合)、このエラーが表示されます。
このカートリッジに直接書き込みを試みるクライアント(テスト版/ベータ版)のリリースを希望されますか？
現在、このカートリッジに使用されているチップに関する情報がないため、書き込み操作を強制しても完全にサポートできるかどうかはわかりません。

Thanks, it was worth a try

I also dumped the newly flashed cart and compared the file with the source rom

Files are identical up to address 0xfff and then start to differ

That partially works - the write operation appears to work, but doesn't work on console

When I dump the newly flashed ROM and compare to the original, it is identical up to address 0xfff and then gets garbled

Sorry for the repeated information, the BBS doesn't seem to work unless I put that header in

弊社のフラッシュカートと同じモードでカートリッジに書き込むだけでは動作しません。
他社製のフラッシュカートリッジの場合、その会社で提供しているデバイスやプログラムで書き込みをする必要があります。
